Run Hasura GraphQL engine using Docker

Introduction

This guide will help you deploy the Hasura GraphQL engine and a Postgres database to store its metadata using Docker Compose.

Deploying Hasura using Docker

Prerequisites

Step 1: Get the docker-compose file

The hasura/graphql-engine/install-manifests repo contains all installation manifests required to deploy Hasura anywhere. Get the docker compose file from there:

# in a new directory run
wget https://raw.githubusercontent.com/hasura/graphql-engine/stable/install-manifests/docker-compose/docker-compose.yaml
# or run
curl https://raw.githubusercontent.com/hasura/graphql-engine/stable/install-manifests/docker-compose/docker-compose.yaml -o docker-compose.yml

Step 2: Run Hasura GraphQL engine

The following command will run Hasura GraphQL engine along with a Postgres database to store its metadata.

$ docker-compose up -d

Check if the containers are running:

$ docker ps

CONTAINER ID IMAGE                 ... CREATED STATUS PORTS          ...
097f58433a2b hasura/graphql-engine ... 1m ago  Up 1m  8080->8080/tcp ...
b0b1aac0508d postgres              ... 1m ago  Up 1m  5432/tcp       ...

Securing the GraphQL endpoint

To make sure that your GraphQL endpoint and the Hasura console are not publicly accessible, you need to configure an admin secret key.

Run the Docker container with an admin-secret env var

graphql-engine:
  image: hasura/graphql-engine:v2.0.0
  environment:
    HASURA_GRAPHQL_METADATA_DATABASE_URL: postgres://postgres:[email protected]:5432/postgres
    HASURA_GRAPHQL_ADMIN_SECRET: myadminsecretkey
  ...

Note

The HASURA_GRAPHQL_ADMIN_SECRET should never be passed from the client to the Hasura GraphQL engine as it would give the client full admin rights to your Hasura instance. See Authentication & Authorization for information on setting up authentication.

Hasura GraphQL engine server logs

You can check the logs of the Hasura GraphQL engine deployed using Docker by checking the logs of the GraphQL engine container:

$ docker ps

CONTAINER ID IMAGE                 ... CREATED STATUS PORTS          ...
097f58433a2b hasura/graphql-engine ... 1m ago  Up 1m  8080->8080/tcp ...
b0b1aac0508d postgres              ... 1m ago  Up 1m  5432/tcp       ...


$ docker logs 097f58433a2b

{"timestamp":"2018-10-09T11:20:32.054+0000", "level":"info", "type":"http-log", "detail":{"status":200, "query_hash":"01640c6dd131826cff44308111ed40d7fbd1cbed", "http_version":"HTTP/1.1", "query_execution_time":3.0177627e-2, "request_id":null, "url":"/v1/graphql", "user":{"x-hasura-role":"admin"}, "ip":"127.0.0.1", "response_size":209329, "method":"POST", "detail":null}}

Updating Hasura GraphQL engine

This guide will help you update the Hasura GraphQL engine running with Docker. This guide assumes that you already have Hasura GraphQL engine running with Docker.

Step 1: Check the latest release version

The current latest version is:

hasura/graphql-engine:latest

All the versions can be found at: https://github.com/hasura/graphql-engine/releases

Step 2: Update the Docker image

In the docker-compose command that you’re running, update the image tag to this latest version.

For example, if you had:

graphql-engine:
  image: hasura/graphql-engine:v1.2.0

you should change it to:

graphql-engine:
  image: hasura/graphql-engine:latest

Note

If you are downgrading to an older version of the GraphQL engine you might need to downgrade your metadata catalogue version as described in Downgrading Hasura GraphQL engine
