Configure environment variables on CircleCI​

The following environment variables must be set for the project on CircleCI via the project settings page, before the project can be built successfully.

VariableDescription
AWS_ACCESS_KEY_IDUsed by the AWS CLI
AWS_SECRET_ACCESS_KEYUsed by the AWS CLI
AWS_DEFAULT_REGIONUsed by the AWS CLI. Example value: "us-east-1" (Please make sure the specified region is supported by the Fargate launch type)
AWS_ACCOUNT_IDAWS account id. This information is required for deployment.
AWS_RESOURCE_NAME_PREFIXPrefix that some of the required AWS resources are assumed to have in their names. The value should correspond to the AWS ECR repository name or aws_resource_prefix variable value in terraform_setup/terraform.tfvars.
DEEPFENCE_CONSOLE_URLDeepfence management console url
FAIL_CVE_COUNTFail the build if number of vulnerabilities found >= this value. Set -1 to pass regardless of vulnerabilities.
FAIL_CRITICAL_CVE_COUNTFail the build if number of critical vulnerabilities found >= this value. Set -1 to pass regardless of critical vulnerabilities.
FAIL_HIGH_CVE_COUNTFail the build if number of high vulnerabilities found >= this value. Set -1 to pass regardless of high vulnerabilities.
FAIL_MEDIUM_CVE_COUNTFail the build if number of medium vulnerabilities found >= this value. Set -1 to pass regardless of medium vulnerabilities.
FAIL_LOW_CVE_COUNTFail the build if number of low vulnerabilities found >= this value. Set -1 to pass regardless of low vulnerabilities.
FAIL_CVE_SCOREFail the build if cumulative CVE score is >= this value. Set -1 to pass regardless of cve score.
