Initialize and Provision your InfluxDBv2.x Container using Docker Init Containers

Proof-of-Concept of Provisioning your InfluxDBv2.x container through Docker Init Containers using Compose files

InfluxDB has already of provisioning the database by using scripts as volume mounts in the /docker-entrypoint-initdb.d directory. See Docker Hub Documentation for InfluxDB under section Custom Initialization Scripts.

This Repository is a proof-of-concept that once achieve similar initialization via the docker init containers in compose file

Usage

docker compose up

Should provide you verbose logs that the default initialization user and a custom user are created via the init-db docker init containers.

Results

• Login into the UI at http://localhost:8086 using the default admin credentials (see influxdb.env)

• Once logged into UI click User Icon on the left-side panel you will observe the provisioned Organization in the bootstrap-influxdb.sh script

• Select the coreOrg organization and click on the user icon on left-side panel and click on Members, you also see the provisioned members

Docker Init Container in Compose

NOTE: this feature is similar to Kubernetes Init Containers, which is available for Docker Compose since version 1.29.

The Init Container can initialize your container by using the depends_on spec. Depending on the intialization process, you can set three conditions of the container's state you wish to initialize:

• service_started
• service_healthy
• service_completed_sucessfully

Unfortunately, this feature is yet to be documented. However, some resources to look into:

1. Feature Request Issue on Docker Compose
2. Pending Pull-Request for Documentation of Init Containers
3. StackExchange Query with a possible example
