Database-hasura

Status of Last Deployment:

Database-hasura is a postgres with hasura instance that manages data and access to it.

Installation

• Use the docker container service with docker-compose to install database-hasura.
• Use the Hasura CLI to manage migration.

Usage

• Dev configuration immediately starts the database snapshot and rolls all migrations.
• After launch, hasura console is available at localhost:8081/console, if it is not disabled in the configuration.
• The ./hasura directory contains the initial configuration for hasura cli.
• When working with the database through the hasura console, the changes will be exported to the migration and metadata directory where the hasura cli was initialized.

Hasura CLI

All commands must be executed in the ./hasura directory or initialized a new directory.

• hasura init - Initialize directory for Hasura GraphQL Engine migrations, but you can use the existing .hasura directory. You will need to specify the configuration in the config.yaml file.

• hasura migrate create baseline --from-server - Exports a snapshot of the current database schema named baseline to the migrations directory.

• hasura metadata export - Exports the entire hasura metadata schema. The uploaded data is placed in the metadata directory.

• hasura console --console-port 8083 - Runs hasura console on localhost:8083/console.

• hasura migrate create <name-of-migration> - Create sql and yaml files required for a migration.

• hasura migrate squash --name "<feature-name>" --from <migration-version> - Squash multiple migrations leading upto the latest one into a single migration file.

• hasura migrate apply --endpoint <server-endpoint> - Apply migrations on the database.

• hasura metadata apply --endpoint <server-endpoint> - Apply Hasura metadata on a database.

• hasura migrate status - Display current status of migrations on a database.

Dev

Build or rebuild services:

docker-compose -f docker-compose.yaml -f docker-compose.dev.yaml build

Builds, (re)creates, starts, and attaches to containers for a service:

docker-compose -f docker-compose.yaml -f docker-compose.dev.yaml up -d

If you want to run hasura for dev, but no migrations:

docker-compose -f docker-compose.yaml -f docker-compose.dev.reup.yaml up -d hasura

Danger zone!

Stops containers and removes containers, networks, volumes, and images created by up.

• Not for production!

- docker-compose -f docker-compose.yaml -f docker-compose.dev.yaml down -v

Prod

Just builds, (re)creates, starts, and attaches to containers for a service:

docker-compose -f docker-compose.yaml -f docker-compose.prod.yaml up -d
