Minio

Since Camel 3.5

Both producer and consumer are supported

The Minio component supports storing and retrieving objects from/to Minio service.

Prerequisites

You must have valid credentials for authorized access to the buckets/folders. More information is available at Minio.

URI Format

minio://bucketName[?options]

The bucket will be created if it doesn’t already exist.
You can append query options to the URI in the following format, ?options=value&option2=value&…​

For example in order to read file hello.txt from the bucket helloBucket, use the following snippet:

from("minio://helloBucket?accessKey=yourAccessKey&secretKey=yourSecretKey&prefix=hello.txt")
  .to("file:/var/downloaded");

URI Options

The Minio component supports 47 options, which are listed below.

Name Description Default Type

Setting the autocreation of the bucket if bucket name not exist.

true

boolean

Reference to a Minio Client object in the registry.

MinioClient

objectLock (common)

Set when creating new bucket.

false

boolean

policy (common)

The policy for this queue to set in the method.

String

proxyPort (common)

TCP/IP port number. 80 and 443 are used as defaults for HTTP and HTTPS.

Integer

region (common)

The region in which Minio client needs to work. When using this parameter, the configuration will expect the lowercase name of the region (for example ap-east-1). You’ll need to use the name Region.EU_WEST_1.id()

String

secure (common)

Flag to indicate to use secure connection to minio service or not.

false

boolean

serverSideEncryption (common)

Server-side encryption.

ServerSideEncryption

serverSideEncryptionCustomer​Key (common)

Server-side encryption for source object while copy/move objects.

ServerSideEncryptionCustomerKey

autoCloseBody (consumer)

If this option is true and includeBody is true, then the MinioObject.close() method will be called on exchange completion. This option is strongly related to includeBody option. In case of setting includeBody to true and autocloseBody to false, it will be up to the caller to close the MinioObject stream. Setting autocloseBody to true, will close the MinioObject stream automatically.

true

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

bypassGovernanceMode (consumer)

Set this flag if you want to bypassGovernanceMode when deleting a particular object.

false

boolean

deleteAfterRead (consumer)

Delete objects from Minio after they have been retrieved. The delete is only performed if the Exchange is committed. If a rollback occurs, the object is not deleted. If this option is false, then the same objects will be retrieve over and over again on the polls. Therefore you need to use the Idempotent Consumer EIP in the route to filter out duplicates. You can filter using the MinioConstants#BUCKET_NAME and MinioConstants#OBJECT_NAME headers, or only the MinioConstants#OBJECT_NAME header.

String

destinationBucketName (consumer)

Source bucket name.

String

destinationObjectName (consumer)

String

includeBody (consumer)

If it is true, the exchange body will be set to a stream to the contents of the file. If false, the headers will be set with the Minio object metadata, but the body will be null. This option is strongly related to autocloseBody option. In case of setting includeBody to true and autocloseBody to false, it will be up to the caller to close the MinioObject stream. Setting autocloseBody to true, will close the MinioObject stream automatically.

true

boolean

includeFolders (consumer)

The flag which is used in the ListObjectsRequest to set include folders.

  • deleteObject

  • deleteObjects

  • listBuckets

  • deleteBucket

  • listObjects

  • getObject (this will return a MinioObject instance)

  • getObjectRange (this will return a MinioObject instance)

Advanced Minio configuration

If your Camel Application is running behind a firewall or if you need to have more control over the MinioClient instance configuration, you can create your own instance and refer to it in your Camel minio component configuration:

from("minio://MyBucket?minioClient=#client&delay=5000&maxMessagesPerPoll=5")
.to("mock:result");

Minio Producer Operation examples

  • CopyObject: this operation copy an object from one bucket to a different one

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(MinioConstants.DESTINATION_BUCKET_NAME, "camelDestinationBucket");
          exchange.getIn().setHeader(MinioConstants.OBJECT_NAME, "camelKey");
          exchange.getIn().setHeader(MinioConstants.DESTINATION_OBJECT_NAME, "camelDestinationKey");
      }
  })
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=copyObject")
  .to("mock:result");

This operation will copy the object with the name expressed in the header camelDestinationKey to the camelDestinationBucket bucket, from the bucket mycamelbucket.

  • DeleteObject: this operation deletes an object from a bucket

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(MinioConstants.OBJECT_NAME, "camelKey");
      }
  })
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=deleteObject")
  .to("mock:result");

This operation will delete the object camelKey from the bucket mycamelbucket.

  • ListBuckets: this operation list the buckets for this account in this region

  from("direct:start")
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=listBuckets")
  .to("mock:result");

This operation will list the buckets for this account

  • DeleteBucket: this operation delete the bucket specified as URI parameter or header

  from("direct:start")
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=deleteBucket")
  .to("mock:result");

This operation will delete the bucket mycamelbucket

  • ListObjects: this operation list object in a specific bucket

  from("direct:start")
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=listObjects")
  .to("mock:result");

This operation will list the objects in the mycamelbucket bucket

  • GetObject: this operation get a single object in a specific bucket

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(MinioConstants.OBJECT_NAME, "camelKey");
      }
  })
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=getObject")
  .to("mock:result");

This operation will return an MinioObject instance related to the camelKey object in mycamelbucket bucket.

  • GetObjectRange: this operation get a single object range in a specific bucket

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(MinioConstants.OBJECT_NAME, "camelKey");
          exchange.getIn().setHeader(MinioConstants.OFFSET, "0");
          exchange.getIn().setHeader(MinioConstants.LENGTH, "9");
      }
  })
  .to("minio://mycamelbucket?minioClient=#minioClient&operation=getObjectRange")
  .to("mock:result");

This operation will return an MinioObject instance related to the camelKey object in mycamelbucket bucket, containing bytes from 0 to 9.

Bucket Autocreation

With the option autoCreateBucket users are able to avoid the autocreation of a Minio Bucket in case it doesn’t exist. The default for this option is true. If set to false any operation on a not-existent bucket in Minio won’t be successful, and an error will be returned.

Automatic detection of Minio client in registry

The component is capable of detecting the presence of a Minio bean into the registry. If it’s the only instance of that type it will be used as client, and you won’t have to define it as uri parameter, like the example above. This may be really useful for smarter configuration of the endpoint.

Moving stuff between a bucket and another bucket

Some users like to consume stuff from a bucket and move the content in a different one without using the copyObject feature of this component. If this is case for you, don’t forget to remove the bucketName header from the incoming exchange of the consumer, otherwise the file will always be overwritten on the same original bucket.

MoveAfterRead consumer option

In addition to deleteAfterRead it has been added another option, moveAfterRead. With this option enabled the consumed object will be moved to a target destinationBucket instead of being only deleted. This will require specifying the destinationBucket option. As example:

  from("minio://mycamelbucket?minioClient=#minioClient&moveAfterRead=true&destinationBucketName=myothercamelbucket")
  .to("mock:result");

In this case the objects consumed will be moved to myothercamelbucket bucket and deleted from the original one (because of deleteAfterRead set to true as default).

Using a POJO as body

Sometimes build a Minio Request can be complex, because of multiple options. We introduce the possibility to use a POJO as body. In Minio there are multiple operations you can submit, as an example for List brokers request, you can do something like:

from("direct:minio")
     .setBody(ListObjectsArgs.builder()
                    .bucket(bucketName)
                    .recursive(getConfiguration().isRecursive())))
     .to("minio://test?minioClient=#minioClient&operation=listObjects&pojoRequest=true")

In this way you’ll pass the request directly without the need of passing headers and options specifically related to this operation.

Dependencies

Maven users will need to add the following dependency to their pom.xml.

pom.xml

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-minio</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel.
