IPFS

Since Camel 2.23

Only producer is supported

The IPFS component provides access to the Interplanetary File System (IPFS).

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ipfs</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

ipfs://cmd?options

Options

The IPFS component supports 4 options, which are listed below.

Name Description Default Type

ipfsHost (producer)

The ipfs host

127.0.0.1

String

ipfsPort (producer)

The ipfs port

5001

int

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

basicPropertyBinding (advanced)

Deprecated Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

Message Headers

Samples

In this sample we add a file to IPFS, get a file from IPFS and finally access the content of an IPFS file.

from("direct:start").to("ipfs:add")
from("direct:start").to("ipfs:get?outdir=target")
from("direct:start").to("ipfs:cat");

Spring Boot Auto-Configuration

When using ipfs with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ipfs-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 5 options, which are listed below.
