Install Third-Party Libraries

Updated Feb 02, 2025 ·

Overview​

To install third-party libraries in a GitLab CI/CD pipeline, you can specify the installation commands in the before_script section. This ensures that necessary libraries are installed before the main pipeline tasks begin, making them available for use during the job execution.

For more information, please see Scripts and job logs.

Pre-requisites​

Modify the pipeline​

Select the project > Build > Pipeline Editor. Paste the code below and commit changes.

workflow:
    name: Generate ASCII Framework 

ascii_job:
    before_script:
        - gem install cowsay
    script:
        - echo "Generating ASCII framework using COWSAY program"
        - cowsay -f dragon "Run for cover, I am a mighty DRAGON!" >> dragon.txt
        - grep -i "dragon" dragon.txt 
        - cat dragon.txt

Go to Jobs > Click the ascii_job.

Using Scripts​

Go back to main page and open the .gitlab-ci.yml file > Edit > Open in Web IDE.

In the Web IDE, create ascii_script.sh and move the contents of the script section here.

Modify the .gitlab-ci.yml file.

workflow:
    name: Generate ASCII Framework 

ascii_job:
    before_script:
        - gem install cowsay
        - chmod +x ./ascii_script.sh
    script:
        - ./ascii_script.sh
    after_script:
        - echo "Done executing."
