GitLab CI: artifacts management

Page content

In this post I will show you how you can pass artifacts between in gitlab CI.

In the previous post we learned the basics of Gitlab CI. I used docker image as an example of artifact in the previous post, but sometimes you need to create other kind of artifacts lik rpm, deb, or a binary, and use this artifacts in the next stage.

  - build
  - deploy

  stage: build
    - echo "File 1" >> ./file1.txt
    - echo "File 2" >> ./file2.txt
    - mkdir dir1
    - echo "dir1 File" >> ./dir1/file.txt
    - mkdir dir2
    - echo "dir2 File" >> ./dir2/file.txt
    - file1.txt
    - dir1/

  stage: deploy
    - ls
    - ls dir1
    - cat file1.txt
    - cat dir1/file.txt

We defined a build with a build and a deploy stage and both has a job with tha same name as tha stage.

In build we create 4 files:

├── dir1
│   └── file.txt
├── dir2
│   └── file.txt
├── file1.txt
└── file2.txt

We can use the artifact property in the .gitlab-ci.yml:

    - file1.txt
    - dir1/
    expire_in: 1 week

Artifacts is used to specify a list of files and directories which should be attached to the build after success. In this example we keep this files for 1 week

In deploy, the following files files - created in build - are available:

├── dir1
│   └── file.txt
├── file1.txt

Then we can use the same file in the deploy stage

Download job artifacts

You can download job artifacts or view the job archive:

  • On the Pipelines page, to the right of the pipeline:

Gitlab artifacts

Upload artifact to Gitlab Generic package registry

Gitlab has its own package registries to store common types of packages for a longer time:

  • Composer
  • Conan
  • Generic
  • Maven
  • npm
  • NuGet
  • PyPI
  • RubyGems

In the nex example I will use the Generic package registry to store files:

image: curlimages/curl:latest

  - upload
  - download

  stage: upload
    - 'curl --header "JOB-TOKEN: $CI_JOB_TOKEN" --upload-file file1.txt "${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/my_package/0.0.1/file1.txt"'

  stage: download
    - 'wget --header="JOB-TOKEN: $CI_JOB_TOKEN" ${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/my_package/0.0.1/file1.txt'
