xmik/chef-server-backup repository overview

⁠docker-chef-server-backup

Debian Jessie with knife-backup⁠ 0.0.11 gem. Base image: ruby:2.2.3-slim. To make Chef Server backup remotely. For Chef Server 11 and 12.

⁠Warning

It won't backup/restore Chef Server 12 users, because of such knife-backup limitation.

⁠Usage

Assuming that:

• your Chef Server is already running and is accessible by chef.example.com
• some Chef Server user exists

Run this docker image e.g. like this:

$ docker run --rm --name chef_server_backup -v ~/.chef/admin.pem:/root/.chef/admin.pem -v /var/backups/chef-server/:/var/backups/chef-server/ -e CHEF_SERVER_URL="https://chef.example.com/organizations/testorg" --link chef_server:chef.example.com xmik/chef-server-backup:0.0.1

where:

• you have to mount pem file for the Chef Server user
• you can mount some directory to /var/backups/chef-server/ inside container or all your backup will be inside container only (it will be lost if using docker run --rm)
• you can set CHEF_USER, default is admin
• you can set PEM_PATH, default is /root/.chef/${CHEF_USER}.pem
• you can set CHEF_SERVER_URL, default is https://chef.example.com/organizations/testorg⁠ , for Chef Server 11 the part "organizations/testorg" is not needed
• you can set KNIFE_COMMAND, default is knife backup export cookbooks roles environments clients users nodes -D /var/backups/chef-server. A good example for testing maybe KNIFE_COMMAND="knife backup export environments -D /var/backups/chef-server". so actually, you can change this command to knife backup restore cookbooks roles environments clients users nodes -D /path/to/exported_backup -y and use this image to restore Chef Server backup
