How to configure the docker service in self hosted runner?

Rafael F_

According to the documentation at: 

https://support.atlassian.com/bitbucket-cloud/docs/pipelines-runners-frequently-asked-questions/

"How do I set up proxy for docker images?

With a self-hosted runner you can use a custom docker-in-docker service.

services:<br>docker:<br>image:&nbsp; &nbsp;docker:dind<br>environment:<br>HTTP_PROXY: "<a href="http://username:password@proxy2.domain.com" rel="noopener nofollow noreferrer" target="_blank">http://username:password@proxy2.domain.com</a>"<br>HTTPS_PROXY: "<a href="http://username:password@proxy2.domain.com" rel="noopener nofollow noreferrer" target="_blank">http://username:password@proxy2.domain.com</a>"


Well, I'm doing that on self hosted runner and getting an error saying that I need to use a self hosted runner....

"The 'services' section in your bitbucket-pipelines.yml file contains a custom docker service. Remove 'image', 'variables' and 'environment' from the docker service definition or use a self-hosted runner for the step."

Below one of the many attempts that failed....

definitions:
    services:
       docker:
          image: docker:dind
           environment:
             HTTP_PROXY: "http://localhost"
             HTTPS_PROXY: "https://localhost"

image: alpine:latest

pipelines:
    branches:
        main:
          - step:
             name: Build Deploy rev-proxy
             runs-on: mylocalrunner
          script:
              - ping localhost -c 1
           services:
                - docker

Hi Rafael,

The runs-on parameter in the yaml file must contain a label named self.hosted. I believe that culprit here is that your yaml file has only the mylocalrunner label, so Pipelines doesn't see that step as a step that will run on your local runner.

You can modify the runs-on parameter as follows:

runs-on:
  - self.hosted
  - mylocalrunner

and this should allow the step to run on your runner. The label mylocalrunner should also exist on the runner you configured on Bitbucket website either from the repository settings or from the workspace settings.

Please feel free to let me know how it goes and if you have any questions!

Kind regards,
Theodora
