6. Select Add variable.

7. Rerun the last pipeline run to verify the secrets are applied correctly.

   1. Alternatively, switch to you application’s source repository in GitLab, make a minor change, and commit it to trigger a new pipeline run.

Procedure

1. Create a project with two files in your preferred text editor, such as Visual Studio Code:

   • env_vars.sh
   • glab-set-vars

2. Update the env_vars.sh file with the following environment variables:

   # env_vars.sh
   
   # GitLab credentials
   export MY_GITLAB_TOKEN="your_gitlab_token_here"
   export MY_GITLAB_USER="your_gitlab_username_here"
   
   export GITOPS_AUTH_PASSWORD="your_OpenShift_GitOps_password_here"
   export GITOPS_AUTH_USERNAME="your_OpenShift_GitOps_username_here"
   
   
   
   // Provide the credentials for the image registry you use.
   # Quay.io credentials
   export QUAY_IO_CREDS_USR="your_quay_username_here"
   export QUAY_IO_CREDS_PSW="your_quay_password_here"
   
   # JFrog Artifactory credenditals
   export ARTIFACTORY_IO_CREDS_USR="your_artifactory_username_here"
   export ARTIFACTORY_IO_CREDS_PSW="your_artifactory_password_here"
   
   # Sonatype Nexus credentials
   export NEXUS_IO_CREDS_USR="your_nexus_username_here"
   export NEXUS_IO_CREDS_PSW="your_nexus_password_here"
   
   # Rekor and TUF routes
   export REKOR_HOST="your rekor server url here"
   export TUF_MIRROR="your tuf service url here"
   
   // Variables required for ACS tasks
   # ROX variables
   export ROX_CENTRAL_ENDPOINT="your_rox_central_endpoint_here"
   export ROX_API_TOKEN="your_rox_api_token_here"
   
   
   // Set these variables if Gitlab CI runners do not run on the same cluster as the {ProductShortName} instance.
   export ROX_CENTRAL_ENDPOINT="your_rox_central_endpoint_here"
   export ROX_API_TOKEN="your_rox_api_token_here"
   
   
   // Variables required for SBOM tasks.
   # Cosign secrets
   export COSIGN_SECRET_PASSWORD="your_cosign_secret_password_here"
   export COSIGN_SECRET_KEY="your_cosign_secret_key_here"
   export COSIGN_PUBLIC_KEY="your_cosign_public_key_here"
   
   # Trustification credentials
   export TRUSTIFICATION_BOMBASTIC_API_URL="your__BOMBASTIC_API_URL_here"

3. Update the glab-set-vars file with the following information:

   #!/bin/bash
   SCRIPTDIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" > /dev/null 2>&1 && pwd)"
   
   if [ $# -ne 1 ]; then
       echo "Missing param, provide gitlab repo name"
       echo "Note: This script uses MY_GITLAB_TOKEN and MY_GITLAB_USER env vars"
       exit
   fi
   
   REPO=$1
   HEADER="PRIVATE-TOKEN: $MY_GITLAB_TOKEN"
   URL=https://gitlab.com/api/v4/projects
   
   # Look up the project ID so we can use it below
   PID=$(curl -s -L --header "$HEADER" "$URL/$MY_GITLAB_USER%2F$REPO" | jq ".id")
   
   function setVars() {
       NAME=$1
       VALUE=$2
       MASKED=${3:-true}
       echo "setting $NAME in https://gitlab.com/$MY_GITLAB_USER/$REPO"
   
       # Delete first because if the secret already exists then its value
       # won't be changed by the POST below
       curl -s --request DELETE --header "$HEADER" "$URL/$PID/variables/$NAME"
   
       # Set the new key/value
       curl -s --request POST --header "$HEADER" "$URL/$PID/variables" \
           --form "key=$NAME" --form "value=$VALUE" --form "masked=$MASKED" | jq
   }
   setVars ROX_CENTRAL_ENDPOINT $ROX_CENTRAL_ENDPOINT
   setVars ROX_API_TOKEN $ROX_API_TOKEN
   
   setVars GITOPS_AUTH_PASSWORD $MY_GITLAB_TOKEN

   setVars QUAY_IO_CREDS_USR $QUAY_IO_CREDS_USR
   setVars QUAY_IO_CREDS_PSW $QUAY_IO_CREDS_PSW
   
   setVars COSIGN_SECRET_PASSWORD $COSIGN_SECRET_PASSWORD
   setVars COSIGN_SECRET_KEY $COSIGN_SECRET_KEY

   setVars TRUSTIFICATION_SUPPORTED_CYCLONEDX_VERSION "$TRUSTIFICATION_SUPPORTED_CYCLONEDX_VERSION"
   
   setVars ARTIFACTORY_IO_CREDS_USR $ARTIFACTORY_IO_CREDS_USR
   setVars ARTIFACTORY_IO_CREDS_PSW $ARTIFACTORY_IO_CREDS_PSW
   
   setVars NEXUS_IO_CREDS_USR $NEXUS_IO_CREDS_USR
   setVars NEXUS_IO_CREDS_PSW $NEXUS_IO_CREDS_PSW
   
   setVars REKOR_HOST $REKOR_HOST

4. (Optional) Modify the glab-set-vars file to disable variables that are not required. For example, to disable setVars ROX_API_TOKEN $ROX_API_TOKEN, add false next to it.

   ROX_API_TOKEN $ROX_API_TOKEN false

5. Load the environment variables into your current shell session:

   source env_vars.sh

6. Make the glab-set-vars script executable, and run it with your repository name to set the variables in your GitLab repository.

   chmod +x glab-set-vars
   
   ./glab-set-vars your_repository_name

7. Rerun the last pipeline run to verify the secrets are applied correctly.
