Use named volumes with Docker

[cgalo5758]

I have the following publish.yaml:

when:
  - event: push
    branch: main

steps:
  build:
    image: hugomods/hugo:base
    commands:
      - build
    volumes:
      - public:/site

It unfortunately results in the following error:

linter publish: steps.build

Insufficient trust level to use volumes

Is there no support for named volumes or are only bind mounts supported?

[anbraten]

Using volumes in general requires the repo to be trusted by an admin.

AFAIK only bind mounts are currently supported:

woodpecker/pipeline/backend/docker/docker.go

Line 204 in 131d4af

hostConfig.Binds = utils.DeduplicateStrings(append(hostConfig.Binds, e.config.volumes...))

I am a little confused about this. Are you saying I can use named volumes if the repo is trusted AND only bind mounts are supported? My apologies if I am missing something obvious.

No, you can't use named volumes currently. I'll convert this into a feature request

Wait a minute. I just tried it and it is working?

This is what I have:

Simple hugo deployment compose.yaml using swarm

services:
  site:
    image: hugomods/hugo:nginx-1.27.4
    networks:
      - proxy
    volumes:
      - public:/site

networks:
  proxy:
    external: true

volumes:
  # This becomes `wiki-cafe-site_public` because swarm prepends the stack name to the volume.
  public:

And my workflow definition .woodpecker/publish.yaml

when:
  - event: push
    branch: main

steps:
  build:
    image: hugomods/hugo:base-0.146.5
    commands:
      - ls -la /
      - pwd
      - hugo build --destination /site
    volumes:
      - wiki-cafe-site_public:/site

Right, then this works just like the docker CLI. Maybe you could open a simple PR to mention this in the docs? ;)
