Hi,

please post the CI config here, the linked repo is private.
I assume you want to build a Docker image and push it to the registry?

Cheers,
Michael

hello Michael, thank you for your reply.
Please let me know what you think the issue could be, I’m only a beginner, so I’m not sure what may be causing it and I spent a lot of time researching this but no luck (I kept creating and deleting projects to see if sth could work).

Hi,

did you build that setup yourself, or where did you copy the parts? From a first peek, it looks like as if the GitLab runner is configured to use the ruby image as default, and none of .gitlab-ci.yml references a different Docker image.

Using Docker executor with image ruby:2.5 ...

This works fine up until you’re calling the build job - which calls the docker CLI command but Docker isn’t installed inside the container.

Funnily enough the push image job works, but push latest fails.

Can you modify the before_script section and add a docker info execution? Possibly you are running into a different error here with Docker.

before_script:
  - docker info
  - docker login -u "gitlab-ci-token" -p "$CI_BUILD_TOKEN" "$CI_REGISTRY"

Cheers,
Michael

I built the project with my team mates - it was a final project for a course I attended and it worked just fine but then I wanted to launch it on my own domain & in my private Gitlab (not the school dedicated one) and ever since then I have had this problem. I have just updated default.conf file with my domain and the pipeline broke on the lint stage with the same ‘docker: command not found’ error…

Ok, I managed to solve this issue - it was caused by the fact that the shared runners were activated (hence gitlab was using ruby instead of shell executor which I chose initially when setting up gitlab runners). uff… thank you so much for your willingness to help, Michael, I appreciate it.

Ah. Shell executor. Now that makes sense, it would have been my next guess that the runner setup now differs :slight_smile: Glad you’ve solved it yourself, nifty CI pipeline overall :slight_smile:

Can you tell me how did you solve it, I am having same issue

Hello, in my case, I went to my project Settings on Gitlab - CI/CD - Runners - deactivate Shared Runners. This solved the issue. I hope it fixes it for you too.

Hi, I am also new to this. And if I disable shared runner then it mentions that no runner found.
My code:

gitlab stages

docker-test:
  stage: docker-test
  script: docker info    # working fine


integration-test:
  image: gradle:alpine
  stage: integration-test
  script:
    - gradle itest --info   # not working

build.gradle code :

task setupTestDB(type :Exec){
    commandLine 'sh','./src/integration/scripts/testDBSetup.sh'
}

task itest(type: Test, dependsOn: "test") {
    description = 'Runs the integration tests.'
    dependsOn setupTestDB
    useTestNG()
    mustRunAfter test
}

testDBSetup.sh :

docker run --rm --name pg_test -d -p 5100:5432 -e POSTGRES_USER=pg -e POSTGRES_PASSWORD=aaaaaa -e POSTGRES_DB=db_test postgres:9.6

And I get the error

Task :setupTestDB FAILED
./src/integration/scripts/testDBSetup.sh: line 5: docker: not found

Hi Michael,now I have the same issue,and I used the Docker executor with image ruby:2.6,the issue comes when I use it in gitlab-ci.yml。。。。May I ask your help?
