Stellar Core on Docker

Refer to SatoshiPay's README since this is based on that with a few additions:

• installation of gcloud and gsutil to allow reading and writing into Google Storage buckets
• including a script to check for liveness (for Kubernetes)

Examples

Checking Liveness

livenessProbe:
  exec:
    command:
      - /liveness/check
      - http://localhost:11626
  initialDelaySeconds: 180
  periodSeconds: 180
  failureThreshold: 10

Enabling History Archive

Set the env ARCHIVE_HISTORY to be the name of the history archive that has the put command. If you started core without this, Stellar recommends that you delete everything -- the database, horizon, and redeploy.

Read/write history in Google Storage

Ensure that you have set ARCHIVE_HISTORY correctly.

GS_SERVICE_ACCOUNT_KEY: if you use Google Storage to write history, set this environment variable to your service account key:

{
  "type": "service_account",
  "project_id": "project-name",
  "private_key_id": "0n7n7cnqp84489",
  "private_key": "-----BEGIN PRIVATE KEY-----..."
}

Your history can then have something like this for read/write:

{
  "local": {
    "get": "/gsutil cp gs://bucket-name/prod/01/{0} {1}",
    "put": "/gsutil cp {0} gs://bucket-name/prod/01/{1}"
}
