[FEATURE] Ability to change cgroupdriver to systemd #293
Description
Is your feature request related to a problem?
When we install kubernetes, it recommends the systemd driver for Docker:
[preflight] Running pre-flight checks
[WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd". Please follow the guide at https://kubernetes.io/docs/setup/cri/
So I try to set it via creating file:
cat > /etc/docker/daemon.json <<EOF
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
},
"storage-driver": "overlay2"
}
EOF
But formula removes it on every state apply.
Other way is to change systemd docker service via setting
ExecStart=/usr/bin/dockerd --exec-opt native.cgroupdriver=systemd
Describe the solution you'd like
Will be good to have this setting in Docker formula.
Describe alternatives you've considered
Alternative is not deleting the /etc/docker/daemon.json file, but separate setting in formula will be much better.

Seems this can be implemented using
docker.pkg.environoption, I'll try this and report results.danny-smit commentedon Jun 20, 2021
The latest version of the formula has support to add settings to the daemon.json. Is that what what you're looking for?
For example:

Thanks, this appears to be the solution. Adding to pillar example may be useful.
