influxdb-setup

Docker script to programmatically setup an InfluxDB 2.0

        

The script was created for usage in docker-compose.yml files (see Usage in Docker Compose). However, you can use it in any environment you want. It is inspired by Eficode's wait-for script.

The script uses the official InfluxDB 2.0 image which ensures compatibility to the specified InfluxDB version. Currently, only InfluxDB 2.0.0-rc is supported, more versions are planned.

The script will wait for a user-defined amount of time until the InfluxDB is available and execute the setup command. If the DB is already set up, it will terminate with exit code 1.

Environment Variables

The script has to be configured via the following (required) environment variables:

• $TIMEOUT - The amount of seconds, the script should try to connect to the database
• $INFLUXDB_SCHEMA - Schema (http or https) of the InfluxDB instance
• $INFLUXDB_HOST - Host of the InfluxDB instance
• $INFLUXDB_PORT - Port of the InfluxDB instance
• $INFLUXDB_USER - The new username
• $INFLUXDB_PW - The new password
• $INFLUXDB_ORG - The new organization
• $INFLUXDB_TOKEN - Access token for the new user
• $INFLUXDB_BUCKETID - Initial BucketID for the new user
• $INFLUXDB_RETENTION - Retention Policy for that bucket - see the InfluxDB Documentation for details
