Migrate to a new minio version

Migrate to a new minio version

Overview

Minio (https://min.io/) is released every week. This article describe a procedure how to upgrate the minio container to a latest with data migration.

Migration procedure

1. Find a latest version

Open docker hub minio images page https://hub.docker.com/r/minio/minio/tags and find out the latest minio release you want to update to:

It should be like: RELEASE.2024-03-05T04-48-44Z

2. Prepare new minio container where to migrate data

Open and update docker-compose.yml (from rpaplatform installation directory, which is by default /opt/rpaplatform) by adding a copy of minio container with the following changes:

  • use container name - minio_new
  • use target image version (image) - f.e. RELEASE.2024-03-05T04-48-44Z
  • change minio data folder (volumes) to a ${STORAGE}/minio_new
  • remove ports section
	minio_new:
	image: "minio/minio:RELEASE.2024-03-05T04-48-44Z"
	restart: "always"
	entrypoint:
	- "/wait-for-it.sh"
	- "-t"
	- "90"
	- "auth-server:8990"
	- "--"
	- "minio"
	- "server"
	- "/data"
	- "--console-address"
	- ":7001"
	volumes:
	- "${STORAGE}/minio_new:/data"
	- "./data/wait-for-it.sh:/wait-for-it.sh"
	environment:
	- "MINIO_ROOT_USER=${MINIO_ACCESS_KEY}"
	- "MINIO_ROOT_PASSWORD=${MINIO_SECRET_KEY}"
	- "MINIO_IDENTITY_OPENID_CONFIG_URL=http://auth-server:8990/authrpa/.well-known/openid-configuration"
	- "MINIO_IDENTITY_OPENID_CLIENT_ID=minio"
	- "MINIO_IDENTITY_OPENID_CLIENT_SECRET=minio-secret"
	- "MINIO_IDENTITY_OPENID_SCOPES=openid"
	- "MINIO_IDENTITY_OPENID_REDIRECT_URI=${CS_PUBLIC_ENDPOINT}:7001/oauth_callback"
	- "MINIO_BROWSER=true"
	logging:
		driver: "json-file"
		options:
		max-file: "5"
		max-size: "10m"

3. Up the new container and migrate data

Run the new container using bash command:

$ docker-compose up -d minio_new

Find out new container id:

$ docker ps | grep minio_new
572987ad887b	 minio/minio:RELEASE.2024-03-05T04-48-44Z									 "/wait-for-it.sh -t …"	 2 weeks ago	 Up 17 hours	 9000/tcp																										 rpaplatform_minio_new_1

Execute migration script inside the new container:

$ docker exec -it	572987ad887b /bin/bash
[root@572987ad887b /]# mc alias set minio_old http://minio:9000 <PASSWORD_MINIO_ACCESS> <PASSWORD_MINIO_SECRET>
[root@572987ad887b /]# mc alias set minio_new http://localhost:9000 <PASSWORD_MINIO_ACCESS> <PASSWORD_MINIO_SECRET>
[root@572987ad887b /]# mc mirror --preserve minio_old minio_new

Wait till migration competed sucesfully.

4. Switch minio comtainer to a new version

Stop the control server and remove the migration container:

$ docker-compose stop
$ docker-compose rm -f minio_new

Backup old data ${STORAGE}/minio and rename ${STORAGE}/minio_new to ${STORAGE}/minio_new (where the STORAGE directory that is defined in .env).

Open and update docker-compose.yml again, remove the minio_new container definition and update the minio container by the new image version (image) - f.e. RELEASE.2024-03-05T04-48-44Z

Start the control server:

$ docker-compose up -d
