GitLab pipeline fail: Unknown option: -c

Question

I have created a pipeline to run a series of jobs that deploy my application to a sandbox environment automatically. My configuration of .gitlab-ci.yml is:

stages:
  - pull
  - build

pull-code-job:
  stage: deploy
  script:
    - cd /usr/share/nginx/html
    - git pull http://myuser:[email protected]/user/my-app.git master

build-code-job:
  stage: deploy
  script:
    - npm install
    - npm run alpha

When I view the pipelines log, I always find that they have failed:

Unknown option: -c

I no call git -c.

My version os GitLab CE is 12.0.3 and the version of git that use runners is 1.7.1.

For every job that you define, the code associated with the pipeline will always be fetched or cloned into the job environment before any of your script, before_script, or after_script sections are run. If you job should be running against the code in the repository, you don't have to git clone or git pull at all; it will happen automatically for you. The output you're seeing in the job is from this automatic fetch.

If you need to, you can disable the automatic fetch using the GIT_STRATEGY variable set to none:

pull-code-job:
  stage: deploy
  variables:
    GIT_STRATEGY: none
  script:
    - cd /usr/share/nginx/html
    - git pull http://myuser:[email protected]/user/my-app.git master

For this job, the repository will not be fetched/cloned from Gitlab. This is useful if you have another job in your pipeline that pulls down your code, then builds an artifact like npm dependencies, compiled binaries from the source code, etc.

Since you're using the shell executor, the job is running directly on the host the runner is on (as opposed to within a Docker container). Looking at the git usage output, there doesn't appear to be a -c option for that git version. Try upgrading git on the host where your gitlab-runner ALPHA is running and run your pipeline again.
