Deploy for different environments from same manual job depending on commit message - gitlab

Question

I have 10 environments. Each environment should have same manual jobs to deploy 5 services (5 buttons). The only difference between environemnt-1 jobs and environment-2 jobs are tags, variables.only check for commit message and environment.name.
E.g. I should be able to specify [staging] in commit message and have 5 separate buttons that deploy 5 services to staging. Same for [production], etc...
staging-deploy-service1:
<<: *deploy
environment:
name: staging
variables:
ServiceName: service2
tags:
- dev-staging
only:
variables:
- $CI_COMMIT_MESSAGE =~ /\[staging\]/
staging-deploy-service2:
<<: *deploy
environment:
name: staging
variables:
ServiceName = service2
tags:
- dev-staging
only:
variables:
- $CI_COMMIT_MESSAGE =~ /\[staging\]/
staging-deploy-service3:
<<: *deploy
environment:
name: staging
variables:
ServiceName: service3
tags:
- dev-staging
only:
variables:
- $CI_COMMIT_MESSAGE =~ /\[staging\]/
staging-deploy-service4:
<<: *deploy
environment:
name: staging
variables:
ServiceName: service4
tags:
- dev-staging
only:
variables:
- $CI_COMMIT_MESSAGE =~ /\[staging\]/
staging-deploy-service5:
<<: *deploy
environment:
name: staging
variables:
ServiceName: service5
tags:
- dev-staging
only:
variables:
- $CI_COMMIT_MESSAGE =~ /\[staging\]/
Currently I have to repeat this block for each environment - 10 times. So it's 50 jobs for just 5 services.
How can I simplify this?

I don't have the perfect solution because having variable substitution in CI tags is still not possible but if we forget the tags, using parallel matrix can do the trick :
.service_name:
parallel:
matrix:
- SERVICE_NAME: ['service1', 'service2', 'service3', 'service4', 'service5']
ENV: ['env1', 'env2', 'env3', 'env4', 'env5']
deploy_service:
<<: *deploy
<<: *service_name
environment:
name: $ENV
script:
- echo $SERVICE_NAME
rules:
- if: '$CI_COMMIT_MESSAGE =~ $ENV'
when: manual
If you really need to keep one tag per environment, you can still simplify your current config using one-dimensional matrix and using more anchors, ex for staging for all services :
.service_name: &service_name
parallel:
matrix:
- SERVICE_NAME: ['service1', 'service2', 'service3', 'service4', 'service5']
.staging_common: &staging_common
environment:
name: $staging
rules:
- if: '$CI_COMMIT_MESSAGE =~ /\[staging\]/'
when: manual
.dev_staging_tags: &dev_staging_tags
tags:
- dev-staging
staging-deploy:
<<: *deploy
<<: *dev_staging_tags
<<: *staging_common
<<: *service_name
script:
- echo $SERVICE_NAME
