Docker Cookbook

The Docker Cookbook provides resources for installing docker as well as building, managing, and running docker containers.

Scope

This cookbook is concerned with the Docker container engine as distributed by Docker, Inc. It does not address Docker ecosystem tooling or prerequisite technology such as cgroups or aufs.

Maintainers

This cookbook is maintained by the Sous Chefs. The Sous Chefs are a community of Chef cookbook maintainers working together to maintain important cookbooks. If you’d like to know more please visit sous-chefs.org or come chat with us on the Chef Community Slack in #sous-chefs.

Requirements

Chef Infra Client 15 or later
Network accessible web server hosting the docker binary.
SELinux permissive/disabled if CentOS Docker Issue #15498

Platform Support

Amazon Linux 2
Debian 9/10
Fedora
Ubuntu 16.04/18.04/20.04
CentOS 7/8

Cookbook Dependencies

This cookbook automatically sets up the upstream Docker package repositories. If you would like to use your own repositories this functionality can be disabled and you can instead setup the repos yourself with yum_repository/apt_repository resources or the chef-apt-docker / chef-yum-docker cookbooks.

Docker Group

If you are not using the official docker repositories you may run into issues with the docker group being different. RHEL is a known issue that defaults to using dockerroot for the service group. Add the group property to the docker_service.

docker_service 'default' do
  group 'dockerroot'
  action [:create, :start]
end

Usage

Add depends 'docker' to your cookbook's metadata.rb
Use the resources shipped in cookbook in a recipe, the same way you'd use core Chef resources (file, template, directory, package, etc).

docker_service 'default' do
  action [:create, :start]
end

docker_image 'busybox' do
  action :pull
end

docker_container 'an-echo-server' do
  repo 'busybox'
  port '1234:1234'
  command "nc -ll -p 1234 -e /bin/cat"
end

Test Cookbooks as Examples

The cookbooks ran under test-kitchen make excellent usage examples.

The test recipes are found at:

Getting Started

Here's a quick example of pulling the latest image and running a container with exposed ports.

# Pull latest image
docker_image 'nginx' do
  tag 'latest'
  action :pull
  notifies :redeploy, 'docker_container[my_nginx]'
end

# Run container mapping containers port 80 to the host's port 80
docker_container 'my_nginx' do
  repo 'nginx'
  tag 'latest'
  port '80:80'
  host_name 'www'
  domain_name 'computers.biz'
  env 'FOO=bar'
  volumes [ '/some/local/files/:/etc/nginx/conf.d' ]
end

You might run a private registry and multiple Docker hosts.

# Login to private registry
docker_registry 'https://registry.computers.biz/' do
  username 'shipper'
  password 'iloveshipping'
  email 'shipper@computers.biz'
end

# Pull tagged image
docker_image 'registry.computers.biz:443/my_project/my_container' do
  tag 'latest'
  action :pull
  host 'tcp://host-1.computers.biz:2376'
end

# Run container
docker_container 'crowsnest' do
  repo 'registry.computers.biz:443/my_project/my_container'
  tag 'latest'
  host 'tcp://host-2.computers.biz:2376'
  tls_verify true
  tls_ca_cert "/path/to/ca.pem"
  tls_client_cert "/path/to/cert.pem"
  tls_client_key "/path/to/key.pem"
  action :run
end

You can manipulate Docker volumes and networks

docker_network 'my_network' do
  subnet '10.9.8.0/24'
  gateway '10.9.8.1'
end

docker_volume 'my_volume' do
  action :create
end

docker_container 'my_container' do
  repo 'alpine'
  tag '3.1'
  command "nc -ll -p 1234 -e /bin/cat"
  volumes 'my_volume:/my_data'
  network_mode 'my_network'
  action :run
end

See full documentation for each resource and action below for more information.

Resources

docker_installation

The docker_installation resource auto-selects one of the below resources with the provider resolution system.

Example

docker_installation 'default'

docker_installation_tarball

The docker_installation_tarball resource copies the precompiled Go binary tarball onto the disk. It should not be used in production, especially with devicemapper.

Example

docker_installation_tarball 'default' do
  version '1.11.0'
  source 'https://my.computers.biz/dist/docker.tgz'
  checksum '97a3f5924b0b831a310efa8bf0a4c91956cd6387c4a8667d27e2b2dd3da67e4d'
  action :create
end

Properties

version - The desired version of docker to fetch.
channel - The docker channel to fetch the tarball from. Default: stable
source - Path to network accessible Docker binary tarball. Ignores version when set.
checksum - SHA-256 checksum of the tarball file.

docker_installation_script

The docker_installation_script resource runs the script hosted by Docker, Inc at http://get.docker.com. It configures package repositories and installs a dynamically compiled binary.

Example

docker_installation_script 'default' do
  repo 'main'
  script_url 'https://my.computers.biz/dist/scripts/docker.sh'
  action :create
end

Properties

repo - One of 'main', 'test', or 'experimental'. Used to calculate script_url in its absence. Defaults to 'main'
script_url - 'URL of script to pipe into /bin/sh as root.

docker_installation_package

The docker_installation_package resource uses the system package manager to install Docker. It relies on the pre-configuration of the system's package repositories. The chef-yum-docker and chef-apt-docker Supermarket cookbooks can be used to use Docker's own repositories.

This is the recommended production installation method.

Example

docker_installation_package 'default' do
  version '20.10.1'
  action :create
  package_options %q|--force-yes -o Dpkg::Options::='--force-confold' -o Dpkg::Options::='--force-all'| # if Ubuntu for example
end

Properties

version - Used to calculate package_version string. This needs to be the complete version (19.03.8).
package_version - Manually specify the package version string
package_name - Name of package to install. Defaults to 'docker-ce'
package_options - Manually specify additional options, like apt-get directives for example
setup_docker_repo - Setup the download.docker.com repo. If you would like to manage the repo yourself so you can use an internal repo then set this to false. default: true on all platforms except Amazon Linux.
repo_channel - The channel of docker to setup from download.docker.com. Only used if setup_docker_repo is true. default: 'stable'

docker_service_manager

The docker_service_manager resource auto-selects a strategy from the docker_service_manager_* group of resources based on platform and version. The docker_service family share a common set of properties.

Example

docker_service_manager 'default' do
  action :start
end

docker_service_manager_execute

Example

docker_service_manager_execute 'default' do
  action :start
end

docker_service_manager_sysvinit

docker_service_manager_sysvinit 'default' do
  host 'unix:///var/run/docker.sock'
  action :stop
end

docker_service_manager_upstart

Example

docker_service_manager_upstart 'default' do
  host ['unix:///var/run/docker.sock', 'tcp://127.0.0.1:2376']
  action :start
end

docker_service_manager_systemd

Example

docker_service_manager_systemd 'default' do
  host ['unix:///var/run/docker.sock', 'tcp://127.0.0.1:2376']
  tls_verify true
  tls_ca_cert "/path/to/ca.pem"
  tls_server_cert "/path/to/server.pem"

  tls_client_key "/path/to/key.pem"
  systemd_opts ["TasksMax=infinity","MountFlags=private"]
  systemd_socket_opts ["Accept=yes"]
  action :start
end

docker_service

The docker_service: resource is a composite resource that uses docker_installation and docker_service_manager resources.

The :create action uses a docker_installation
The :delete action uses a docker_installation
The :start action uses a docker_service_manager
The :stop action uses a docker_service_manager

The service management strategy for the host platform is dynamically chosen based on platform, but can be overridden.

Example

docker_service 'tls_test:2376' do
  host [ "tcp://#{node['ipaddress']}:2376", 'unix:///var/run/docker.sock' ]
  tls_verify true
  tls_ca_cert '/path/to/ca.pem'
  tls_server_cert '/path/to/server.pem'
  tls_server_key '/path/to/server-key.pem'
  tls_client_cert '/path/to/client.pem'
  tls_client_key '/path/to/client-key.pem'
  action [:create, :start]
end

:import - Imports an image from a tarball at destination
:remove - Removes (untags) an image
:push - Pushes an image to the registry

Properties

The docker_image resource properties mostly corresponds to the Docker Engine API as driven by the docker-api Ruby gem

A docker_image's full identifier is a string in the form <repo>:<tag>. There is some nuance around naming using the
public registry vs a private one.

repo - aka image_name - The first half of a Docker image's identity. This is a string in the form: registry:port/owner/image_name. If the registry:port portion is left off, Docker will implicitly use the Docker public registry. "Official Images" omit the owner part. This means a repo id can be as short as busybox, alpine, or centos. These names refer to official images on the public registry. Names can be as long as my.computers.biz:5043/what/ever to refer to custom images on an private registry. Often you'll see something like chef/chef to refer to private images on the public registry. - Defaults to resource name.
tag - The second half of a Docker image's identity. - Defaults to latest
source - Path to input for the :import, :build and :build_if_missing actions. For building, this can be a Dockerfile, a tarball containing a Dockerfile in its root, or a directory containing a Dockerfile. For :import, this should be a tarball containing Docker formatted image, as generated with :save.
destination - Path for output from the :save action.
force - A force boolean used in various actions - Defaults to false
nocache - Used in :build operations. - Defaults to false
noprune - Used in :remove operations - Defaults to false
rm - Remove intermediate containers after a successful build (default behavior) - Defaults to true
read_timeout - May need to increase for long image builds/pulls
write_timeout - May need to increase for long image builds/pulls
host - A string containing the host the API should communicate with. Defaults to ENV['DOCKER_HOST'] if set.
tls - Use TLS; implied by --tlsverify. Defaults to ENV['DOCKER_TLS'] if set.
tls_verify - Use TLS and verify the remote. Defaults to ENV['DOCKER_TLS_VERIFY'] if set
tls_ca_cert - Trust certs signed only by this CA. Defaults to ENV['DOCKER_CERT_PATH'] if set.
tls_client_cert - Path to TLS certificate file for docker cli. Defaults to ENV['DOCKER_CERT_PATH'] if set
tls_client_key - Path to TLS key file for docker cli. Defaults to ENV['DOCKER_CERT_PATH'] if set.

Examples

docker_image 'image_1' do
  tag 'v0.1.0'
  source '/src/myproject/container1/Dockerfile'
  action :build
end

build from a directory, only if image is missing

docker_image 'image_2' do
  tag 'v0.1.0'
  source '/src/myproject/container2'
  action :build_if_missing
end

build from a tarball NOTE: this is not an "export" tarball generated from an an image save. The contents should be a Dockerfile, and anything it references to COPY or ADD

docker_image 'image_3' do
  tag 'v0.1.0'
  source '/tmp/image_3.tar'
  action :build
end

docker_image 'hello-again' do
  tag 'v0.1.0'
  source '/tmp/hello-world.tar'
  action :import
end

docker_image 'my.computers.biz:5043/someara/hello-again' do
  action :push
end

Connect to an external docker daemon and pull an image

docker_image 'alpine' do
  host 'tcp://127.0.0.1:2376'
  tag '2.7'
end

docker_image_prune

The docker_image_prune is responsible for pruning Docker images from the system. It speaks directly to the Docker Engine API.
Note - this is best implemented by subscribing to docker_image changes. There is no need to to clean up old images upon each converge. It is best done at the end of a chef run (delayed) only if a new image was pulled.

Actions

:prune - Delete unused images

Properties

The docker_image_prune resource properties map to filters

dangling - When set to true (or 1), prune only unused and untagged images. When set to false (or 0), all unused images are pruned
prune_until - Prune images created before this timestamp. The <timestamp> can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the daemon machine’s time.
with_label/without_label - (label=<key>, label=<key>=<value>, label!=<key>, or label!=<key>=<value>) Prune images with (or without, in case label!=... is used) the specified labels.
host - A string containing the host the API should communicate with. Defaults to ENV['DOCKER_HOST'] if set.

Examples

default action, default properties

docker_image_prune 'prune-old-images'

All filters

docker_image_prune "prune-old-images" do
  dangling true
  prune_until '1h30m'
  with_label 'com.example.vendor=ACME'
  without_label 'no_prune'
  action :prune
end

docker_tag

Docker tags work very much like hard links in a Unix filesystem. They are just references to an existing image. Therefore, the docker_tag resource has taken inspiration from the Chef link resource.

Actions

:tag - Tags the image

Properties

target_repo - The repo half of the source image identifier.
target_tag - The tag half of the source image identifier.
to_repo - The repo half of the new image identifier
to_tag- The tag half of the new image identifier

Examples

docker_tag 'private repo tag for hello-again:1.0.1' do
  target_repo 'hello-again'
  target_tag 'v0.1.0'
  to_repo 'localhost:5043/someara/hello-again'
  to_tag 'latest'
  action :tag
end

docker_container

The docker_container is responsible for managing Docker container actions. It speaks directly to the Docker remote API.

Containers are process oriented, and move through an event cycle. Thanks to Glider Labs for this excellent diagram. alt tag

Actions

:create - Creates the container but does not start it. Useful for Volume containers.
:start - Starts the container. Useful for containers that run jobs.. command that exit.

userns_mode - Modify the user namespace mode - Defaults to nil, example option: host
pid_mode - Set the PID (Process) Namespace mode for the container. host: use the host's PID namespace inside the container.
ipc_mode - Set the IPC mode for the container - Defaults to nil, example option: host
uts_mode - Set the UTS namespace mode for the container. The UTS namespace is for setting the hostname and the domain that is visible to running processes in that namespace. By default, all containers, including those with --network=host, have their own UTS namespace. The host setting will result in the container using the same UTS namespace as the host. Note that --hostname is invalid in host UTS mode.
ro_rootfs - Mount the container's root filesystem as read only using the --read-only flag. Defaults to false

Examples

Create a container without starting it.

docker_container 'hello-world' do
  command '/hello'
  action :create
end

This will exit succesfully. It will happen on every chef-client run.

docker_container 'busybox_ls' do
  repo 'busybox'
  command 'ls -la /'
  action :run
end

The :run action contains both :create and :start the container in one action. Redeploys the container on resource change. It is the default action.

docker_container 'alpine_ls' do
  repo 'alpine'
  tag '3.1'
  command 'ls -la /'
  action :run
end

Set environment variables in a container

docker_container 'env' do
  repo 'debian'
  env ['PATH=/usr/bin', 'FOO=bar']
  command 'env'
  action :run
end

docker_container 'env_files' do
  repo 'debian'
  env_file lazy { ['/env_file1', '/env_file2'] }
  command 'env'
  action :run
end

This process remains running between chef-client runs, :run will do nothing on subsequent converges.

docker_container 'an_echo_server' do
  repo 'alpine'
  tag '3.1'
  command 'nc -ll -p 7 -e /bin/cat'
  port '7:7'
  action :run
end

  port '5007:7/udp'
  action :run
end

docker_container 'chef_container' do
  command 'true'
  volumes '/opt/chef'
  action :create
end

  repo 'debian'
  volumes_from 'chef_container'
end

Set a container's entrypoint

docker_container 'ohai_again_debian' do
  repo 'debian'
  volumes_from 'chef_container'
  entrypoint '/opt/chef/embedded/bin/ohai'
  command 'platform'
  action :run_if_missing
end

Automatically remove a container after it exits

docker_container 'sean_was_here' do
  command "touch /opt/chef/sean_was_here-#{Time.new.strftime('%Y%m%d%H%M')}"

7.0.0 (2020-08-31)

Breaking Change

The 7.0 release includes a breaking change to package installs with version specified. Before this change RHEL based systems allowed specifying any valid version string (19, 19.03, 19.03.8) and an * was added automatically to package name for specified version installation. New change specifies docker-ce package name and uses package resource version option to specify version. The version option default has been removed and thus will default to the lastest version. If version option is specified it'll lock the package to that version. Debian family machines are unaffected by the change. With this change we will not need to constantly release new versions of the cookbook for new releases of Docker.

Breaking Changes

Default to Docker 17.12.0
Remove previously deprecated support for Debian 7 / CentOS 6. Currently supported released of Docker do not run on these platforms.
Removed support for the EOL Docker 1.12.3
Removed the ChefSpec matchers which are no longer needed with ChefDK 2.X
Remove the broken legacy binary installation resource. This was only used by very old EOL docker releases
By default setup the apt/yum repos in the package install resource so that out of the box there's no need for additional cookbooks. If you would like to manage your own docker repos or other internal repos this may be disabled by property. Due to this change the cookbook now requires Chef 12.15+

v0.37.0

Please note some important changes with this release:

The sysconfig DOCKER_OPTS improvement in #250 can potentially change the behavior of that environment variable as it now allows shell interpolation of any embedded variables. This should not affect most environments. If your DOCKER_OPTS does contains any expected $, please escape via \$ for previous behavior or be sure it will behave as expected before upgrading.
The daemon restart option (which is deprecated) has been defaulted to nil instead of false when node['docker']['container_init_type'] is set to prevent issues with container restart policies. If you're dependent on the daemon option, please be sure to update your node['docker']['restart'] appropriately.
This release also defaults systemd docker host to fd:// to match upstream, enabling socket activation properly. Adjust node['docker']['host'] if necessary.

0.35.0

After a long personal hiatus (sorry!), this is the last minor release before 1.0 of the cookbook. If you can handle the Docker port number change and don't use anything deprecated, upgrading to 1.0.X from 0.35.X of the cookbook should be very easy.

This release has a bunch of changes and hasn't been fully tested yet. Wanted to get it out there for broad testing. Please use caution!

Major kudos to @tduffield for the #147 PR, which includes:

Binary Installation
- Added missing dependency resolution for using the binary.
Dependency Checks
- Added docker::dep_check that will take an action if certain dependencies are not met.
- node[docker][alert_on_error_action] = :fatal will kill the chef run and print the error message.
- node[docker][alert_on_error_action] = :warn will print the error message but continue with the chef run. There is no guarantee that it will succeed though.
KitchenCI
- Copied MiniTests to ServerSpec Tests
- Added new platforms (Debian 7.4)
- Changed provisioner from chef-solo to chef-zero
- Removed Ubuntu 12.10 because it is not supported by Docker and the Kernel is bad and fails all the tests.
- Removed tests for the source recipe. The dotcloud/docker repo actually doesn't build any Go deliverables.
- I think that the source recipe needs to be completely refactored.

If you're using CentOS/RHEL with EPEL, upcoming docker-io 0.9.0 package upgrade can be tracked at Bugzilla 1074880

This release includes Docker 0.9.0 changes and defaults, such as setting exec_driver to libcontainer ("native"), setting -rm on docker build, double dash arguments on the CLI, additional flags, etc.

DEPRECATED: Rename storage_type attribute to storage_driver to match Docker terminology (storage_type will be removed in chef-docker 1.0)

0.31.0

Lots of init love this release. Now supporting runit.

Please note change of storage_type attribute from devmapper to devicemapper (and associated recipe name change) to match docker's name for the driver.

Cookbook now automatically adds -s option to init configurations if storage_type is defined, which is it by default. If you were specifying -s in the options attribute, you no longer need to do so. In my quick testing, docker daemon doesn't seem to mind if -s is specified twice on startup, although you'll probably want to get rid of the extra specification.

I've also dropped the LANG= and LC_ALL= locale environment settings from the Upstart job configuration. Its not specified in the default docker job. Please open an issue in docker project and here if for some reason this is actually necessary.

Bugfix: Match devicemapper storage_type attribute to match docker driver name (along with recipe name)
Enhancement: #72: Add initial runit init_type
