Examples help you to understand how to test TerraCost.
Cloud Provider pricing data 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=terracost mysql:8.0.34 --default-authentication-plugin=mysql_native_password
Once Mysql started, create the terracost database
mysql -h 127.0.0.1 -uroot -pterracost -e "CREATE DATABASE terracost_test"
To start prices ingestion you need to first decide which cloud provider to ingest. In the example AWS is available with -ingest-aws.
go run terracost.go -ingest-aws -minimal
Here we ingest all supported services by TerraCost, ingestion could takes several minutes depending the amounts of data.
If you don't need all services you can run it with -minimal which will run just the small subset needed for it work.
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:terracost@tcp(127.0.0.1:3306)/terracost_test?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
