Build docker image

To build a new docker image from source you just run the build script with a git tag as parameter.

This can now be run on a linux for amd64. By running cross compiling of the go code and only add files when building the docker image it works without running it on a Raspberry Pi.

Example:

./build.sh v3.4.10

NOTE! To make the correct OS and architecture be specified for the image the build is done with the experimental buildx docker feature. To use it you must make sure experimental mode is enabled for the docker client by adding "experimental":"enabled" to ~/.docker/config.json.

Image are pushed to docker hub.

Start etcd docker image

The environment variable GOMAXPROCS specifies how many CPU cores the Go process will use. If you only run etcd on the RPi use 4 cores to use the full capacity. All parameters for the image are forwarded to the etcd process.

docker run -d --env GOMAXPROCS=4 -v /var/lib/etcd:/var/lib/etcd -p 2379:2379 -p 2380:2380
