gitlab-ci lesson learn

- dont forget to use . when create .gitlab-ci.yaml file

- put it on root directory and it will auto detected by gitlab system

- setting up runner (ask help from SRE team)

- put sensitif data in gitlab ci variable

    tools : filetobase64

    use this code below to decode from base64 to file

    - echo $YOUR_GITLAB_CI_VARIABLE | base64 -di > your-file-name.extension

- use docker image version same as local version of sdk

    example : image: ghcr.io/cirruslabs/flutter:3.13.2

    will be better if we clone the image to our server

- gitlab ci script does not support multi line, make it single line and separate each script with semicolon ;

- use rules instead of only or except becaus they are deprecated

- don't forget to use tags: or your pipeline will not detected by runner

- generate version from git tag

#!/bin/bash

# Set ENVIRONMENT to either "sandbox" or "prod" for testing
ENVIRONMENT="sandbox"
BUILD_NUMBER=""

# Example for testing:
if [ "$ENVIRONMENT" != "prod" ]; then
    BUILD_NUMBER="20012003"  # Example 8 digits for sandbox
elif [ "$ENVIRONMENT" == "prod" ]; then
    BUILD_NUMBER="201002"    # Example 6 digits for prod
fi

# Generate the build name based on the length of the BUILD_NUMBER
if [ ${#BUILD_NUMBER} -eq 8 ]; then
    # Sandbox format: 8 digits -> 2.1.2.30 (apply the same logic as prod)
    BUILD_NAME=$(echo $BUILD_NUMBER | sed -r 's/^([0-9])([0-9]{0,1})([0-9]{1,2})([0-9]{1,2})([0-9]{2})$/\1.\2\3.\4.\5/' | sed -r 's/\.0([0-9])/\.\1/g; s/\.0+([1-9][0-9]*)/\.\1/g; s/^([0-9]+)\.0+([0-9]+)/\1.\2/')
