Solution 1: Go Packages and Functions

Explore how to implement Go packages and functions within a GitLab CI/CD pipeline. Understand the process of building, tagging, and pushing Docker images to Docker Hub, and see how Go code execution integrates into the pipeline stages. Gain practical knowledge of managing Go modules and automating deployment workflows.

We'll cover the following...

Solution

Here is the implementation of how to use GitLab CI/CD to push Docker images to Docker Hub. The script.sh file provided in the playground below contains all the necessary commands to successfully push Docker images to Docker Hub using GitLab CI/CD.

Note: Before moving forward with code execution, kindly provide values for the following variables: user_email, user_name, and repo_url.

image: docker:stable

services:
    - name: docker
      alias: docker

stages:
  - build
  - run

compile:
  stage: build
  script:
    - docker build -t $USERNAME/gitlab_task_img .
    - echo $PASSWORD | docker login -u $USERNAME --password-stdin
    - docker push $USERNAME/gitlab_task_img:latest
    - echo "Image has been pushed successfully :D :D"
  artifacts:
    paths:
      - bin/

execute:
  stage: run
  script:
    - docker pull $USERNAME/gitlab_task_img:latest
    - docker run $USERNAME/gitlab_task_img:latest /bin/sh run_go_file.sh
main.go

Code explanation

The .gitlab-ci.yml file

We’ll now look at the .gitlab-ci.yml file and the main.go file provided in the solution.

Let’s first look at the .gitlab-ci.yml file to get us started:

YAML
image: docker:stable
services:
    - name: docker
      alias: docker
stages:
  - download
  - execute
compile:
  stage: download
  script:
    - docker build -t $USERNAME/gitlab_task_img .
    - echo $PASSWORD | docker login -u $USERNAME --password-stdin
    - docker push $USERNAME/gitlab_task_img:latest
    - echo "Image has been pushed successfully :D :D"
  artifacts:
    paths:
      - bin/
execute:
  stage: execute
  script:
    - docker pull $USERNAME/gitlab_task_img:latest
    - docker run $USERNAME/gitlab_task_img:latest /bin/sh run_go_file.sh

Let’s break down the GitLab CI/CD configuration file .gitlab-ci.yml:

  • The image: docker:stable line specifies that the GitLab CI/CD runner should use the docker:stable Docker image as its base image. This image includes the Docker client, allowing us to build and interact with Docker images and containers within the CI/CD pipeline.

  • The services section defines additional services that should be linked to the CI/CD runner. In this case, it includes the ...
