MinFS is a fuse driver for Amazon S3 compatible object storage server. MinFS lets you mount a remote bucket (from a S3 compatible object store), as if it were a local directory. This allows you to read and write from the remote bucket just by operating on the local mount directory.
MinFS helps legacy applications use modern object stores with minimal config changes. MinFS uses BoltDB for caching and saving metadata, list of files, permissions, owners etc.
Be careful, it is always possible to remove boltdb cache. Cache will be recreated by MinFS synchronizing metadata from the server.
Download the pre-built RPMs from here
yum install minfs-0.0.20170226202056-1.x86_64.rpmCreate a new config.json in /etc/minfs directory with your S3 server access and secret keys.
This example uses play.minio.io:9000
{"version":"1","accessKey":"Q3AM3UQ867SPQQA43P2F","secretKey":"zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"}Create an /etc/fstab entry
https://play.minio.io:9000/mybucket /mnt/mounted/mybucket minfs defaults,cache=/tmp/mybucket 0 0
Now proceed to mount fstab entry.
mount /mnt/mounted/mybucketVerify if mybucket is mounted and is accessible.
ls -F /mnt/mounted/mybucket
etc/ issue
MinFS can also be used via the MinFS Docker volume plugin. You can mount a local folder onto a Docker container, without having to go through the dependency installation or the mount and unmount operations of MinFS.
- Docker Engine v1.13.0 and above.
Use docker-compose to create a volume using the plugin and share the volume with other containers. In the example below the volume is created using the minfs plugin and and used by nginx container to serve the static content from the bucket.
version: '2'
services:
my-test-server:
image: nginx
ports:
- "80:80"
volumes:
- my-test-store:/usr/share/nginx/html:ro
volumes:
my-test-store:
driver: minio/minfs
driver_opts:
endpoint: https://play.minio.io:9000
access-key: Q3AM3UQ867SPQQA43P2F
secret-key: zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG
bucket: testbucket
opts: cache=/tmp/my-test-storePlease change the `endpoint`, `access-key`, `secret-key` and `bucket` for your local Minio setup.
Once you have successfully created docker-compose.yml configuration in your current working directory.
docker-compose upOne can even manually install the plugin, create and the volume using docker.
Install the plugin
docker plugin install minio/minfsCreate a docker volume my-test-store using minio/minfs driver.
docker volume create -d minio/minfs \
--name my-test-store \
-o endpoint=https://play.minio.io:9000 \
-o access-key=Q3AM3UQ867SPQQA43P2F \
-o secret-key=zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG \
-o bucket=testbucket
-o opts=cache=/tmp/my-test-storePlease change the `endpoint`, `access-key`, `secret-key`, `bucket` and `opts` for your local Minio setup.
Once you have successfully created the volume, start a new container with my-test-store attached.
In the example below nginx container is run to serve pages from the new volume.
docker run -d --name my-test-server -p 80:80 -v my-test-store:/usr/share/nginx/html:ro nginxEither of the above steps create a MinFS based volume for a Nginx container. Verify if your nginx container is running properly and serving content.
