May change in future +releases or be removed completely. + +You can specify the depth of fetching and cloning using `GIT_DEPTH`. This allows +shallow cloning of the repository which can significantly speed up cloning for +repositories with a large number of commits or old, large binaries. The value is +passed to `git fetch` and `git clone`. + +>**Note:** +If you use a depth of 1 and have a queue of builds or retry +builds, jobs may fail. + +Since Git fetching and cloning is based on a ref, such as a branch name, runners +can't clone a specific commit SHA. If there are multiple builds in the queue, or +you are retrying an old build, the commit to be tested needs to be within the +git history that is cloned. Setting too small a value for `GIT_DEPTH` can make +it impossible to run these old commits. You will see `unresolved reference` in +build logs. You should then reconsider changing `GIT_DEPTH` to a higher value. + +Builds that rely on `git describe` may not work correctly when `GIT_DEPTH` is +set since only part of the git history is present. + +To fetch or clone only the last 3 commits: +``` +variables: + GIT_DEPTH: "3" +``` + ## Hidden jobs >**Note:** |
