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.
Create the folder to share between our 4 nodes:
Run this on all nodes:
About my path SOURCE:
mnt
is for things sharedminio
is the driver or the applications used to sharedev-d
is my cluster ID. It could beprod-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..

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.

Blobs are a common abstraction for storing unstructured data on Cloud storageservices and accessing them via HTTP. This guide shows how to work withblobs in the Go CDK.
The blob
package supports operations like reading and writing blobs (using standardio
package interfaces), deleting blobs, and listing blobs in a bucket.
Subpackages contain driver implementations of blob for various services,including Cloud and on-prem solutions. You can develop your applicationlocally using fileblob
, then deploy it to multiple Cloud providers withminimal initialization reconfiguration.
Opening a Bucket🔗
The first step in interacting with unstructured storage isto instantiate a portable *blob.Bucket
for your storage service.
The easiest way to do so is to use blob.OpenBucket
and a service-specific URLpointing to the bucket, making sure you “blank import” the driver package tolink it in.
See Concepts: URLs for general background and the guide below for URL usagefor each supported service.
Alternatively, if you needfine-grained control over the connection settings, you can call the constructorfunction in the driver package directly.
You may find the wire
package useful for managing your initialization codewhen switching between different backing services.
See the guide below for constructor usage for each supported service.
Prefixed Buckets🔗
You can wrap a *blob.Bucket
to always operate on a subfolder of the bucketusing blob.PrefixedBucket
:
Alternatively, you can configure the prefix directly in the blob.OpenBucket
URL:
Using a Bucket🔗
Once you have opened a bucket for the storage provider you want, you canstore and access data from it using the standard Go I/O patterns describedbelow. Other operations like listing and reading metadata are documented in theblob
package documentation.
Writing Data to a Bucket🔗
To write data to a bucket, you create a writer, write data to it, and thenclose the writer. Closing the writer commits the write to the provider,flushing any buffers, and releases any resources used while writing, so youmust always check the error of Close
.
The writer implements io.Writer
, so you can use any functions that takean io.Writer
like io.Copy
or fmt.Fprintln
.
In some cases, you may want to cancel an in-progress write to avoid the blobbeing created or overwritten. A typical reason for wanting to cancel a writeis encountering an error in the stream your program is copying from. To aborta write, you cancel the Context
you pass to the writer. Again, you mustalways Close
the writer to release the resources, but in this case you canignore the error because the write’s failure is expected.
Reading Data from a Bucket🔗
Once you have written data to a bucket, you can read it back by creating areader. The reader implements io.Reader
, so you can use any functionsthat take an io.Reader
like io.Copy
or io/ioutil.ReadAll
. You mustalways close a reader after using it to avoid leaking resources.
Minio Generate Random Access Keyword
Many storage providers provide efficient random-access to data in buckets. Tostart reading from an arbitrary offset in the blob, use NewRangeReader
.
Minio Generate Random Access Key Free
Deleting a Bucket🔗
You can delete blobs using the Bucket.Delete
method.
Other Usage Samples🔗
Supported Storage Services🔗
Google Cloud Storage🔗
Google Cloud Storage (GCS) URLs in the Go CDK closely resemble the URLsyou would see in the gsutil
CLI.
blob.OpenBucket
will use Application Default Credentials; if you haveauthenticated via gcloud auth login
, it will use those credentials. SeeApplication Default Credentials to learn about authenticationalternatives, including using environment variables.
Full details about acceptable URLs can be found under the API reference forgcsblob.URLOpener
.
GCS Constructor🔗
The gcsblob.OpenBucket
constructor opens a GCS bucket. You must firstcreate a *net/http.Client
that sends requests authorized by Google CloudPlatform credentials. (You can reuse the same client for anyother API that takes in a *gcp.HTTPClient
.) You can find functions in thegocloud.dev/gcp
package to set this up for you.
Minio Generate Random Access Key Code
S3🔗
S3 URLs in the Go CDK closely resemble the URLs you would see in the AWS CLI.You should specify the region
query parameter to ensure your applicationconnects to the correct region.
blob.OpenBucket
will create a default AWS Session with theSharedConfigEnable
option enabled; if you have authenticated with the AWS CLI,it will use those credentials. See AWS Session to learn about authenticationalternatives, including using environment variables.
Full details about acceptable URLs can be found under the API reference fors3blob.URLOpener
.
S3 Constructor🔗
The s3blob.OpenBucket
constructor opens an S3 bucket. You must firstcreate an AWS session with the same region as your bucket:
S3-Compatible Servers🔗
The Go CDK can also interact with S3-compatible storage servers thatrecognize the same REST HTTP endpoints as S3, like Minio, Ceph, orSeaweedFS. You can change the endpoint by changing the Endpoint
fieldon the *aws.Config
you pass to s3blob.OpenBucket
. If you are usingblob.OpenBucket
, you can switch endpoints by using the S3 URL using queryparameters like so:
See aws.ConfigFromURLParams
for more details on supported URL options for S3.
Azure Blob Storage🔗
Azure Blob Storage URLs in the Go CDK allow you to identify Azure Blob Storage containerswhen opening a bucket with blob.OpenBucket
. Go CDK uses the environmentvariables AZURE_STORAGE_ACCOUNT
, AZURE_STORAGE_KEY
, andAZURE_STORAGE_SAS_TOKEN
to configure the credentials. AZURE_STORAGE_ACCOUNT
is required, along with one of the other two.
Full details about acceptable URLs can be found under the API reference forazureblob.URLOpener
.
Azure Blob Constructor🔗
The azureblob.OpenBucket
constructor opens an Azure Blob Storage container.azureblob
operates on Azure Storage Block Blobs. You must first createAzure Storage credentials and then create an Azure Storage pipeline beforeyou can open a container.
Local Storage🔗
The Go CDK provides blob drivers for storing data in memory and on the localfilesystem. These are primarily intended for testing and local development,but may be useful in production scenarios where an NFS mount is used.
Local storage URLs take the form of either mem://
or file:///
URLs.Memory URLs are always mem://
with no other information and always create anew bucket. File URLs convert slashes to the operating system’s native fileseparator, so on Windows, C:foobar
would be written asfile:///C:/foo/bar
.
