git pre-commit hooks library

cf.  https://codimd.nomadic-labs.com/p/YcXmjg1qv#/4

pre-commit is a tool that helps to configure git pre-commit hooks, with an abundance of already configured scripts

pre-commit install and configuration

• Install in system

(apt-get / brew ) install pre-commit

• install in repo 

then in each repo clone (set-up pre-commit for this repo):

pre-commit install

• then (configure) edit .pre-commit-config.yaml

.pre-commit-config.yaml example  (from https://gitlab.com/tezos/tezos/-/blob/master/.pre-commit-config.yaml?ref_type=heads )

General Notes about pre-commits

• runs only against staged files

 

• to run manually :

pre-commit run --all-files

• to run 1 check specifically  (example : run only  1 plugin (shfmt) )

pre-commit run shfmt

terraform variable <-> variables {script, gitlab-ci}

 (Ici, ce que vous voulez avant le lien) (Ici vous racontez votre vie)

terraform -> gitlab/script/etc.

src: https://stackoverflow.com/questions/75531444/how-to-use-terraform-variable-into-gitlab-ci-yml

• Terraform : use an "output" 

locals {

toto = format ("${var.ressource_name_pattern}-something", "cloudfront-edge")

}

output "toto" {

 value = local.toto

}

• Script: get output from terraform command

foobar = ${terraform output toto}

gitlab -> Terraform

Read environment variables in terraform variables, add TF_VAR_ in front of the variable name,

=> env / exported  "TF_VAR_toto" => variable.tf variable toto
















terraform -> gitlab/script/etc. VARIABLE (in project settings)

     For example : create an EKS cluster & then create a variable with the KUBECONFIG data in another project which has the code for the apps & trigger the deployment of those apps into newly created cluster using that variable.




    - terragrunt run-all apply --terragrunt-non-interactive -auto-approve tfplan-$CI_COMMIT_SHA
    - terraform output kubectl_config > kubectl_config
    - |
      curl -s -XPUT -H "PRIVATE-TOKEN: $GITLAB_API_RW_PRIVATE_TOKEN" $CI_API_V4_URL/groups/$GROUP_ID/variables/KUBECONFIG \
      --form "value=$(cat kubectl_config)" \
      --form "variable_type=file" \
      --form "protected=false" \
      --form "masked=false" \ 

      --form "environment_scope=*"
