This Go program is a compatibility shim to allow the easy control of docker containers via systemd service units.
You basically have two options to install this Go program package:
- If you have Go installed and configured on your PATH, just do the following go get inside your GOPATH to get the latest version:
go get -u github.com/mback2k/docker-systemd-shim
- If you do not have Go installed and just want to use a released binary, then you can just go ahead and download a pre-compiled Linux amd64 binary from the Github releases.
Finally put the docker-systemd-shim binary onto your PATH and make sure it is executable.
The following is an example of a systemd.service unit file which uses this shim to control a container:
[Unit]
Description=Docker container: your-container-name
Wants=network.target
After=docker.service
Requires=docker.service
# You could also specify dependencies on other units, including those managed with this shim
#After=your-other-container.service
#Requires=your-other-container.service
[Service]
Type=notify
ExecStart=/usr/local/sbin/docker-systemd-shim -container your-container-name
Environment=DOCKER_API_VERSION=1.38
Restart=on-failure
PrivateTmp=true
ProtectHome=true
ProtectSystem=full
[Install]
# You could either make this service start, stop and restart together with docker
WantedBy=docker.service
# or make it just start and stop with the system, but not restart with docker
#WantedBy=multi-user.target
Replace your-container-name with the name of the container you want to control with this unit file.
This tool is meant as a supplement to standalone or unmanaged Docker containers and not as a replacement for Kubernetes, Docker Swarm or the docker run CLI command. This tool can only control previously created and already existing docker containers.
I personally use this tool to manage pre-requisite containers for my Docker Swarm cluster, for example ndppd and tinc running inside containers managed via Ansible.
