[QUESTION] https Docker proxy configuration

[Gsyltc]

Hi,

I want to run diun using an https docker proxy (with tecnativa/docker-socket-proxy).

Here my configuration :

service:
    image: crazymax/diun:latest
    volumes:
      - data:/data
    environment:
      TZ: "Canada/Eastern"
      LOG_LEVEL: "info"
      LOG_JSON: "false"
      DIUN_WATCH_WORKERS: 5
      DIUN_WATCH_SCHEDULE: "${DIUN_WATCH_SCHEDULE}"
      DIUN_WATCH_JITTER: "30s"
      DIUN_WATCH_FIRSTCHECKNOTIF: "true"
      DIUN_WATCH_RUNONSTARTUP: "true"
      DIUN_WATCH_COMPAREDIGEST: "true"
      DIUN_PROVIDERS_SWARM: "true"
      DIUN_PROVIDERS_SWARM_WATCHBYDEFAULT: "false"
      DIUN_PROVIDERS_SWARM_ENDPOINT: "https://docker-proxy.mydomain"
      DIUN_DB_PATH: "/data/diun.db"

My docker proxy have those grant and run on 5 nodes (swarm managers) :

• IMAGES : 1
• CONTAINERS : 1
• VERSION : 1
  and is behind a Traefik.

For testing, I try to grant ALL functions for the proxy.

Diun containers can reach the docker proxy (test with wget, in http and https)
When I run the container I got this error

ERR Cannot create Docker client error="invalid character 'M' looking for beginning of value" provider=swarm

Do you have any idea what’s wrong?

Docker version : 29.1.2
Docker API : 1.52. Try to set DIUN_PROVIDERS_SWARM_APIVERSION in the diun container but no changes.

Try to set DIUN_PROVIDERS_SWARM_TLSCERTSPATH="" and DIUN_PROVIDERS_SWARM_TLSVERIFY=true (and false). and no changes

Thanks

Hi,
my suggestion would be to use github.com/wollomatic/socket-proxy — it's tailored for Traefik. I attached a non-swarm docker-compose for reference.
docker-compose_example.yml

(it`s a docker rootlees)

@urbanswelt Thanks, I will check it.
