Examples help you to understand how to test Terracost.
Cloud Provider pricing datas need to be ingested in a Mysql server. For testing purpose, local docker can be used
docker run -p 3306:3306 -d --privileged -e MYSQL_ROOT_PASSWORD=password mysql:8.0.21 --default-authentication-plugin=mysql_native_password
# Once Mysql started, create the terracost database
mysql -h 127.0.0.1 -uroot -ppassword -e "CREATE DATABASE terracost"
To start prices ingestion you need to first decide which cloud provider to ingest. In the example AWS is available with -ingest-aws.
and services
in terracost-ingester.go
go run terracost.go -ingest-aws
Here we ingest all supported services by Terracost, ingestion could takes severals minutes depending the amonts of datas. If you don't need all services, the list could be defined to reduce time.
Note Before to ingest datas, the database migrations are needed. In order to correctly run migrations, we need
?multiStatements=trueparam on DB connectorsql.Open("mysql", "root:password@tcp(127.0.0.1:3306)/terracost?multiStatements=true")
To estimate a terraform plan, you need to first generate it as json format
terraform init
terraform plan -out update.tfplan
terraform show -json update.tfplan > terraform-plan.json
Then run the estimation by specifying your json plan file path.
go run terracost.go -estimate-plan ./terraform-plan.json
To estimate terraform code, define the terraform provider to use and the path of your terraform hcl code.
go run terracost.go -estimate-hcl-provider aws -estimate-hcl ../testdata/aws/stack-aws
