Axiom

Hasura presales demo kit

Quickstart

To get started, first copy template files into the correct locations:

cp .hasura/context.yaml.template .hasura/context.yaml
cp .env.template .env
cp .env.local.template .env.local

Next, create a build using these environment files:

# Create a basic supergraph
ddn run build-local-s1

Finally, set up the demo databases and start your supergraph:

# Initiate the demo databases and connect to them
ddn run docker-start-local

Command Documentation

Each of the ddn run commands in .hasura/context.yaml corresponds to both a different way to build your supergraph and which source databases to use

Command	Database Location	Description
docker-start	Any	Overrides standard message with customer axiom instructions
docker-stop	Any	Stops and removes all Docker containers and volumes related to the current setup
build-local-s1	Local	Builds a basic supergraph with one data domain and one data source
build-local-s2	Local	Builds a supergraph with one data domain, multiple data sources and global functions
build-local-s3	Local	Builds a full/complex supergraph with multiple data domains and data sources
build-local-s4	Local	Builds a complex supergraph and adds mutations
docker-start-local	Local	Initiates the telco demo datasources locally and starts the local Hasura DDN containers
demo-telco	Telco	Starts the containers for the telco demo data sources locally
demo-healthcare	Healthcare	Not yet implemented
demo-banking	Banking	Not yet implemented

Connectors

Deleting connectors

Sometimes the number of connectors in cloud will surpass the max (100) and it will be required to clear out old connectors.

A handy script has been created to quickly and easily delete older connectors from cloud

Caution

This is a destructive command and will prevent your cloud supergraph from working correctly. Use with caution!

# Delete the 20 oldest connector builds from the default environment in .hasura/context.yaml
./scripts/connector-delete.sh default 20

Deploying new connectors

The simplest way to deploy new connectors is to run a new supergraph build in each region. It's important to ensure that the connector regions match the regions you're deploying to so this process takes all that into account.

This full rebuild deployment will run a 'build up' of 4 progressively more complex supergraph before running the standard metadata deploy for JWT/NoAuth

# Run the deploy script
./scripts/deploy/deploy.mjs

# Set the region (default points to axiom-test)
# ? Select a context region to set: default
# A complete rebuild will redeploy connectors. Do not use this if you have only altered metadata/hml files
# ? Do you want to perform a complete rebuild? yes

Important

Hasura Note: Following a connector update, it's important to update all the .env.cloud.* file details in Monday.com with the new locations/bearer tokens etc. These are not stored in the repo for obvious reasons.

Deploying new metadata

Any metadata change that you've tested locally and against axiom-test can be rolled out in a couple of seconds with the deploy script. The deploy script will run a JWT deployment and a No-Auth deployment before applying No-Auth as the project API.

# Run the deploy script
./scripts/deploy/deploy.mjs

# ? Select a context region to set: default
# ? Do you want to perform a complete rebuild? no

Supported regions

The most up-to-date list is in .hasura/context.yaml and mirrored in the deploy script. We're currently deployed with axiom supergraphs in:

• Australia
• Europe
• Singapore
• US East
• US West
