CIO Volume With Minio
Minio is an object storage server compatible with Amazon S3 API. It is suited for storing unstructured data such as photos, videos, log files, backups and container images.
Using CIO volumes with Minio is a great way to setup a highly available S3 compatible cloud storage service for development and testing environments.
In this recipe we use a Docker Stack file to define the Minio service and the CIO volume. Then, using a single command, we can create and launch the Minio instance with highly available persistent storage.
1. Prerequisites
- Familiarity with Docker Stack.
- CIO installed on your machine. Install from here
2. Create Docker secrets for Minio
echo "secret" | docker secret create access_key -
echo "mysecret" | docker secret create secret_key -
3. Run Minio on Docker Stack
To deploy the Minio service on Docker Stack, save the following into a minio.yml file in your current working directory. Docker will pull the Minio image and CIO will create the minio1-data volume using the pre-defined MINIO profile.
version: '3.1'
services:
minio1:
image: minio/minio
volumes:
- minio1-data:/export
ports:
- "9001:9000"
networks:
- minionet
deploy:
restart_policy:
delay: 10s
max_attempts: 10
window: 60s
command: server /export
secrets:
- secret_key
- access_key
volumes:
minio1-data:
driver: cio
driver_opts:
profile: "MINIO"
networks:
minionet:
driver: overlay
secrets:
secret_key:
external: true
access_key:
external: true
Then run command
docker stack deploy --compose-file=minio.yml minio
The Minio instance is now available on the cluster at port 9001 and is accessible from any IP address of the cio cluster. List the node IPs with the cio nodes
command:
$ cio nodes
NODENAME IP NODE_ID ROLE STATUS
c1 192.168.3.95 4132353b sds normal
c2 192.168.3.53 dceacd20 backup1 normal
c3 192.168.3.145 9ee22782 backup2 normal
c4 192.168.3.129 d2004822 standard normal
In the above example, point the browser at any of the IP addresses, e.g. http://192.168.3.95:9001.
Login in with access key “secret” and secret key “mysecret” configured earlier.
