            ]
        }
    ]
}

GitLab
#

GitLab Project
#

Create a folder s3-data for the files that should be pushed into the S3 bucket.

# Repository folder structure
deploy-into_s3
├── .gitlab-ci.yml
└── s3-data
    ├── File1.txt
    └── File2.txt

GitLab Variables
#

Add the Access keys of your IAM user as variables to the GitLab project.

  • Go to: Settings > CI/CD

  • Expand the Variables section and add the IAM credentials:

# Variable 1
AWS_ACCESS_KEY_ID

# Variable 1 Value
AKIAIOSFODNN7EXAMPLE

# Variable 2
AWS_SECRET_ACCESS_KEY

# Variable 2 Value

GitLab CI Pipeline
#

Add the GitLab CI pipeline to the repository:

# .gitlab-ci.yml
stages:
  - deploy

deploy-into_s3:
  stage: deploy
  image: python:latest
  script:
    - pip install awscli
    - aws s3 cp ./s3-data s3://jkw-gitlab/ --recursive
  only:
    - main

The pipeline job will start automatically and every time new data is pushed to the GitLab repository.


Wait till pipeline completes
#

  • Go to Build > Jobs and click on the job for the logs.
# Job logs

$ aws s3 cp ./s3-data s3://jkw-gitlab/ --recursive
upload: s3-data/File1.txt to s3://jkw-gitlab/File1.txt           
upload: s3-data/File2.txt to s3://jkw-gitlab/File2.txt
