Hasura GraphQL API Engine #

In this tutorial, you will deploy your own Hasura GraphQL Engine. We will explain all the necessary SetOps commands that we need to deploy the application. You can find a summary of all commands at the end.

Prepare your SetOps Environment #

💡 At first, you need to choose a name for project, stage, and app. You can edit them in the form in the top right corner.

1. Let’s start by creating a Project.

   setops project:create <PROJECT>
   

2. Create a Stage for your project.

   setops -p <PROJECT> stage:create <STAGE>
   

   project and stage must only contain lowercase letters a-z and numbers 0-9 and start with a lowercase letter. The length of project has to be between 3 and 20 characters and the length of stage between 3 and 12. It also has to start with a lowercase letter. A valid example is parkscheibe & staging.

3. Create the App web.

   setops -p <PROJECT> -s <STAGE> app:create <APPNAME>
   

   The name for apps must only contain lowercase letters a-z and numbers 0-9 and dashes -. The name must be between 3 and 16 characters long and start with a lowercase letter.

   We want it to be publicly reachable, so we set the network’s public option to true.

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> network:set public true
   

   The default exposed port of the Server is 8080, so let’s change it:

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> network:set port 8080
   

   The Health Check path deviates from the default path (/), so you need to adjust the network Health Check as well.

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> network:set health-check-path '/healthz'
   

   Last you need to set some environment variables to run the GraphQL Engine:

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> env:set HASURA_GRAPHQL_ENABLE_CONSOLE=true
   setops -p <PROJECT> -s <STAGE> --app <APPNAME> env:set HASURA_GRAPHQL_DEV_MODE=true
   setops -p <PROJECT> -s <STAGE> --app <APPNAME> env:set HASURA_GRAPHQL_ENABLED_LOG_TYPES="startup, http-log, webhook-log, websocket-log, query-log"
   setops -p <PROJECT> -s <STAGE> --app <APPNAME> env:set HASURA_GRAPHQL_ADMIN_SECRET=setopsftw
   

4. Create the Services the App needs.

   We need to create a PostgreSQL Service and link it to the App <APPNAME>.

   setops -p <PROJECT> -s <STAGE> service:create database --type postgresql11 --plan shared
   setops -p <PROJECT> -s <STAGE> --app <APPNAME> link:create database --env-key HASURA_GRAPHQL_DATABASE_URL
   

   Next we need to install the PostgreSQL Extension pgcrypto:

   setops -p <PROJECT> -s <STAGE> --service database option:set extensions pgcrypto
   

5. Commit your Changeset.

   setops -p <PROJECT> -s <STAGE> changeset:commit
   

Deploy your Image #

You need to pull the application image in order to deploy it with SetOps. We use the Docker Image from dockerhub. You can use our Dockerfile for your own apps, too.

6. Pull and deploy your Image

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> release:deploy hasura/graphql-engine:latest
   

   release:deploy executes all required steps to deploy a new image to SetOps. You can find more information about the distinct steps and how to run them isolated here.

7. Verify your app status is RUNNING.

   setops -p <PROJECT> -s <STAGE> app:info <APPNAME>
   

8. Open the application in your browser.

   Copy the domain in format web.staging.project.$YOURDOMAIN.

   setops -p <PROJECT> -s <STAGE> --app <APPNAME> domain
   

   You can log in with the secret defined in the environment variable: setopsftw.

Enjoy!
