Deployment management

Generating a airnode-feed deployment

• Run the script

pnpm generate-airnode-feed-deployment

• Select the API.

$ ts-node src/config-generation/airnode-feed/generate-deployment.ts
? Select an API to create deployment: › - Use arrow-keys. Return to submit.
❯   api-1
    api-2
    some-api
    ...

• Select the deployment type.

? Select the deployment type: › - Use arrow-keys. Return to submit.
❯   staging
    candidate

• Deployment will be created under ./data/apis/<api-name>/deployments/<deployment_type>-deployments.

Managing deployments

• Deployment folder for the each API has the below structure:

.
├── active-deployments
└── candidate-deployments
    └── api3-20231101-airnode-feed.json

• Deployments names are created in this format: api3-YYYYMMDD-airnode-feed.json and there should be only one or no deployments under candidate-deployments.
• Once a candidate-deployment is deployed by the API provider, deployment under the candidate-deployment will be manually moved under active-deployments. active-deployments will be confirmed with CI scripts. If there is no heartbeat from the deployment, CI won't allow pushing changes to the repository.
• Deployments will identified by airnode-feed configuration file's hash.

Heartbeat

Airnode feed minutely log the below string and the string will be parsed and returned through an API for this repository to check deployments.

${airnodeAddress} - ${stage} - ${airnodeFeedVersion} - ${currentTimestamp} - ${deploymentTimestamp} - ${airnodeFeedConfigHash} - ${heartbeatSignature}

Through the airnodeFeedConfigHash it will be possible to check if the correct deployment is deployed.

api-data.json

There is api-data.json file for each API provider in data/apis/<api-name>/api-data.json path. This file includes the below information.

• alias: Unique alias used for API.
• name: Name of the API for public use.
• airnode: Airnode address of the API.
• xpub: Extended public key.
• supportedFeedsInBatches: Name of the data feeds in batches supported by API, seperated by OIS titles.
• deploymentLocations: Deployment locations where API provider deployed their Airnode feed to.
• homepageUrl: API provider's website's homepage URL.
• verifiedBaseUrl: URL where includes API provider's Airnode address in it's TXT records for people to be able to be confirm the Airnode address.
• signedApiUrl: URL for the Signed API deployed by the API provider.
• productionSignedApiUrls: URLs of the Signed APIs where Airnode feeds deployed by the API provider push data to.
• stagingSignedApiUrl: URL of the Signed API where staging Airnode feed deployed by the API provider push data to.

Adding a new data feed

• Create a blueprint for the feed using pnpm add-blueprint

> @phase21/api-integrations@1.5.0 add-blueprint /home/m3/meto_ws/api3_ws/byog/PHASE-2.1/final/api-integrations
> ts-node src/config-generation/add-new-data-feed-blueprint.ts

✔ Write data feed's name: … SOMETHING/USD
✔ Select an API to create data feed: › nodary
✔ Select the OIS: › Nodary
✔ Write the value for the parameter "path" (leave empty to pass)": … /feed/latest
✔ Write the value for the parameter "name" (leave empty to pass)": … SOMETHING/USD
✔ Write post processing snippet for "SOMETHING/USD": … (response) => { return response.value }

• Add data feed to the corresponding supportedFeedsInBatches in corresponding api-data.json
• Run pnpm sync-oises
