Docker image for Chef Server

This Dockerfile installs and configures Chef Server. It installs and configures Postfix for email notifications as well. Also, It creates admin user with password admin123 by default. Please reset the password, email address and keys.

This Dockerfile has been tested with Chef Server v12.19.31.

How to use this image

Pull the image from Docker hub

docker pull sunggun/chef-server

Run the Container

Run:

docker run -d \
  --name chef-server \
  -p 443:443 \
  sunggun/chef-server

Please check the log when you run/start/restart the chef-server. It takes a while until fully startup.

docker logs -f chef-server

To verify chef-server version:

docker exec -it chef-server cat /opt/opscode/version-manifest.json | grep build_version

Using volume for data storage

The Dockerfile defines mount points i order to support storing config, data ,and data backup in your storage.

  • /etc/opscode: Chef server home.
  • /var/opt/opscode: Data directory for all components.
  • /var/opt/chef-backup: Data backup directory. If you run the chef-server-ctl backup in the running container, the backup data archive will be stored in this directory.
docker run -d \
  --name chef-server \
  -v <your-chef-home-directory>:/etc/opscode:rw \
  -v <your-data-directory>:/var/opt/opscode:rw \
  -v <your-backup-directory>:/var/opt/chef-backup:rw \
  -h <your-hostname> \
  -p 443:443 \

Build the Image

Build latest version: current latest is 12.19.31

docker build -t chef-server:latest -t chef-server:12.19.31 .

For my workflow :-)

docker build -t sunggun/chef-server:latest -t sunggun/chef-server:12.19.31 .

To build the chef-server image with specific version such as 12.19.31, you need to pass CHEF_SERVER_VERSION and CHEF_SERVER_DOWNLOAD_SHA256 build-arg. Please find the VERSION and SHA256 for Ubuntu Linux 18.04 x86_64 from https://downloads.chef.io/chef-server/ubuntu/
