@thewinger In case you do not directly mount the docker.sock into the autoheal container you should provide an alternative method to reach the docker socket. If the alternative method is a socket proxy (via TCP connection) you should set the address of it in the DOCKER_SOCK environment variable. You added the socket_proxy network to the autoheal container on which the socket proxy container is located, this is good. So "you have to instruct" autoheal to use a TCP connection instead of direct docker socket access.

I tried to pair willfarrell/autoheal with tprasadtp/docker-socket-proxy, but found the same issue.
autoheal:
image: willfarrell/autoheal:latest
container_name: autoheal
depends_on:
- socketproxy
networks:
- socketproxynet
environment:
DOCKER_SOCK: tcp://socketproxy:2375
AUTOHEAL_INTERVAL: 5
AUTOHEAL_START_PERIOD: 0
AUTOHEAL_DEFAULT_STOP_TIMEOUT: 30
labels:
diun.enable: "true"
restart: unless-stopped
2020-12-07T07:36:27.214593318Z /docker-entrypoint: exec: line 101: autoheal: not found
Other containers (Watchtower, Diun, Portainer) works well with this companion.
@thewinger Have you added the DOCKER_SOCK environment variable instead of mounting the docker sock directly to your autoheal container?

@zhorvath83 have not tried to. I just wen with the default and used the
volume:
- /var/run/docker.sock:/var/run/docker.sock
from docker-autoheal.

I don't really have the knowledge to follow you up.
I tried adding
DOCKER_SOCK: tcp//socket-proxy:2375
but did not work.

@thewinger A colon is missing, otherwise everything is fine with it. It should look like this in your case:
In the autoheal docker container's compose you should include this:
environment:
DOCKER_SOCK: tcp://socket-proxy:2375
The next step is to configure the endpoint access rights on the socket proxy. For a test only, I allowed access to ALL endpoints (value 1) but it didn't worked. Ultimately, I am struggling with the same problem as you: autoheal doesen't starts in companion of socket proxy.
socketproxy:
container_name: socketproxy
image: ghcr.io/tprasadtp/docker-socket-proxy
networks:
- socketproxynet
privileged: true
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"

Same issue here, is there a fix for this?

Here is a fix in two patches.
First patch add tcp support without ssl. Use tcp:// or tcps:// with DOCKER_SOCK.
Second patch fixes "not found" problem.
