• Many storage providers provide efficient random-access to data in buckets. To start reading from an arbitrary offset in the blob, use NewRangeReader. // Open the key 'foo.txt' for reading at offset 1024 and read up to 4096 bytes.

The goal

I want to share/sync a common folder between 4 nodes.
You know like dropbox but without a 3td party server of course.
Let's see if (Minio Erasure Code) can help.

This doc is not on Minio website yet but it really helped me.

This will spit out a long random string. Copy it and paste it in the first following command, and set the second one to whatever you’d like: $ export MINIOSECRETKEY=yourlongrandomstringhere $ export MINIOACCESSKEY=loginname Similarly, let’s go ahead and set the root login the same way. MinIO Custom Access and Secret Keys using Docker secrets To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as Docker secrets. MinIO server also allows regular strings as access and secret keys.

Create the folder to share between our 4 nodes:

Run this on all nodes:

About my path SOURCE:

• mnt is for things shared
• minio is the driver or the applications used to share
• dev-d is my cluster ID. It could be prod-a, prod-b, dev-b ...

Network

Run this the leader node:

Deploying 4 instances (Minio Erasure Code)

Run this the leader node:

Create your own MINIO_ACCESS_KEY and MINIO_SECRET_KEY values!

• Ensure access key = 5 to 20 characters
• Ensure secret key = 8 to 40 characters

docker service ls

logs from minio1

Status 1)

The services are running good.

Create a bucket

• Open a new tab on your browser
• Go to: http://ip10_0_25_6-9001.play-with-docker.com/minio
• Enter credits
• Create bucket 'tester'
• Upload a picture 'animated-good-job.gif' from the browser

On your 4 nodes, check if the file is there:

Status 2)

When uploading a file from the web GUI, all nodes sync the files as expected. Good!

2/2 Testing file sharing by creating a file from the nodes

Then ...

from node3, Create dummy files (unit test)

You get the pattern at this point :)

from node4, Create dummy files (unit test)

You get the pattern at this point :)

Status 3)

Files are NOT SYNCED when they are created from the nodes. Is it normal?

Asking for help on Slack

Hello folks!

Regarding Minio Erasure Code Mode,
I want to share/sync a common folder between 4 nodes using Erasure Code Mode.
You know like dropbox (but without a 3td party main server of course).

I took many hours to test this setup and this is my conclusion:

• When uploading a file from the web GUI, all nodes sync the files as expected. Good!
• But files are NOT SYNCED when they are created from the nodes. Damm :-/

May I ask your help here?

mounting a common DIR you can either use MinFS or S3FS

[8:18]
which would mount the relevant bucket on the nodes..

OK tell me about it :)))

OMG!
You guys are doing this as well?!
You saved the day!

The missing part - Install the volume driver

docker volume create

Testing the volume within a container

Status 4)

By using our docker volume bucket-dev-e we can mount the bucket into any container. Very good!

Using sub directories from a bucket.

This part is work in progress. See https://github.com/minio/minfs/issues/20

For all details about my setup, please check my post:
The complete guide to attach a Docker volume with Minio on your Docker Swarm Cluster

— — —

Let’s say that my Minio's bucket is named: bucket-dev-e.
I mounted it here /mnt/minio00000/dev-e using docker volume create …

Let's start one blog (This works perfectly):

What if I need to run multiple websites:

My challange is … the commands above are not working. By default we cannot specify subpaths bucket-dev-e/ghost/site2/images from a Docker Volume.
What can we do ? (I DON’T KNOW THE ANSWER YET)

I don't want to use one Docker Volume for each of the 100x (potentially 1000x) site I’m hosting.

Any other ideas?

Conclusion

By using Minio along their minfs (https://github.com/minio/minfs) we can have best of both worlds.
A solid object storage and connect Docker volume to this storage. Any container can have access to the bucket created in Minio.

Another great thing with Minio is that you don't have to pre-define disk space (like GlusterFS, Infinit, Portworx, etc). Minio use whatever space you have a disk.

You can also create another data store easily on hyper.sh and rock to the world. It's been a long journey and now this will help me to move to production.

Configuration Directory

Till MinIO release RELEASE.2018-08-02T23-11-36Z, MinIO server configuration file (config.json) was stored in the configuration directory specified by --config-dir or defaulted to ${HOME}/.minio. However from releases after RELEASE.2018-08-18T03-49-57Z, the configuration file (only), has been migrated to the storage backend (storage backend is the directory passed to MinIO server while starting the server).

You can specify the location of your existing config using --config-dir, MinIO will migrate the config.json to your backend storage. Your current config.json will be renamed upon successful migration as config.json.deprecated in your current --config-dir. All your existing configurations are honored after this migration.

Additionally --config-dir is now a legacy option which will is scheduled for removal in future, so please update your local startup, ansible scripts accordingly.

MinIO also encrypts all the config, IAM and policies content if KMS is configured. Please refer to how to encrypt your config and IAM credentials here

Certificate Directory

TLS certificates by default are stored under ${HOME}/.minio/certs directory. You need to place certificates here to enable HTTPS based access. Read more about How to secure access to MinIO server with TLS.

Following is the directory structure for MinIO server with TLS certificates.

You can provide a custom certs directory using --certs-dir command line option.

Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely MINIO_ROOT_USER and MINIO_ROOT_PASSWORD. Using the combination of these two values MinIO encrypts the config stored at the backend.

Region

or environment variables

Example:

Storage Class

By default, parity for objects with standard storage class is set to N/2, and parity for objects with reduced redundancy storage class objects is set to 2. Read more about storage class support in MinIO server here.

or environment variables

Cache

MinIO provides caching storage tier for primarily gateway deployments, allowing you to cache content for faster reads, cost savings on repeated downloads from the cloud.

or environment variables

Etcd

MinIO supports storing encrypted IAM assets and bucket DNS records on etcd.

NOTE: if path_prefix is set then MinIO will not federate your buckets, namespaced IAM assets are assumed as isolated tenants, only buckets are considered globally unique but performing a lookup with a bucket which belongs to a different tenant will fail unlike federated setups where MinIO would port-forward and route the request to relevant cluster accordingly. This is a special feature, federated deployments should not need to set path_prefix.

or environment variables

API

By default, there is no limitation on the number of concurrent requests that a server/cluster processes at the same time. However, it is possible to impose such limitation using the API subsystem. Read more about throttling limitation in MinIO server here.

or environment variables

Notifications

Notification targets supported by MinIO are in the following list. To configure individual targets please refer to more detailed documentation here

Accessing configuration

All configuration changes can be made using mc admin config get/set/reset/export/import commands.

List all config keys available

Obtain help for each key

e.g: mc admin config set myminio/ etcd returns available etcd config args

To get ENV equivalent for each config args use --env flag

This behavior is consistent across all keys, each key self documents itself with valid examples.

Dynamic systems without restarting server

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.

NOTE: if you set any of the following sub-system configuration using ENVs, dynamic behavior is not supported.

Usage scanner

Data usage scanner is enabled by default. The following configuration settings allow for more staggered delay in terms of usage calculation. The scanner adapts to the system speed and completely pauses when the system is under load. It is possible to adjust the speed of the scanner and thereby the latency of updates being reflected. The delays between each operation of the scanner can be adjusted by the mc admin config set alias/ delay=15.0. By default the value is 10.0. This means the scanner will sleep 10x the time each operation takes.

In most setups this will keep the scanner slow enough to not impact overall system performance. Setting the delay key to a lower value will make the scanner faster and setting it to 0 will make the scanner run at full speed (not recommended in production). Setting it to a higher value will make the scanner slower, consuming less resources with the trade off of not collecting metrics for operations like healing and disk usage as fast.

Example: Following setting will decrease the scanner speed by a factor of 3, reducing the system resource use, but increasing the latency of updates being reflected.

Once set the scanner settings are automatically applied without the need for server restarts.

NOTE: Data usage scanner is not supported under Gateway deployments.

Healing

Healing is enabled by default. The following configuration settings allow for more staggered delay in terms of healing. The healing system by default adapts to the system speed and pauses up to '1sec' per object when the system has max_io number of concurrent requests. It is possible to adjust the max_delay and max_io values thereby increasing the healing speed. The delays between each operation of the healer can be adjusted by the mc admin config set alias/ max_delay=1s and maximum concurrent requests allowed before we start slowing things down can be configured with mc admin config set alias/ max_io=30 . By default the wait delay is 1sec beyond 10 concurrent operations. This means the healer will sleep 1 second at max for each heal operation if there are more than 10 concurrent client requests.

In most setups this is sufficient to heal the content after drive replacements. Setting max_delay to a lower value and setting max_io to a higher value would make heal go faster.

Example: The following settings will increase the heal operation speed by allowing healing operation to run without delay up to 100 concurrent requests, and the maximum delay between each heal operation is set to 300ms.

Once set the healer settings are automatically applied without the need for server restarts.

NOTE: Healing is not supported under Gateway deployments.

Environment only settings (not in config)

Browser

Enable or disable access to web UI. By default it is set to on. You may override this field with MINIO_BROWSER environment variable.

Example:

Minio Generate Random Access Key Generator

Domain

By default, MinIO supports path-style requests that are of the format http://mydomain.com/bucket/object. MINIO_DOMAIN environment variable is used to enable virtual-host-style requests. If the request Host header matches with (.+).mydomain.com then the matched pattern $1 is used as bucket and the path is used as object. More information on path-style and virtual-host-style here
Example:

For advanced use cases MINIO_DOMAIN environment variable supports multiple-domains with comma separated values.
