StreamSets Data Collector is open source software for building dataflows quickly and easily, spanning on-premises, multi-cloud and edge infrastructure.

It has an advanced and easy to use User Interface that allows data scientists, developers and data infrastructure teams easily create data pipelines in a fraction of the time typically required to create complex ingest scenarios.

Basic Usage

docker run --restart on-failure -p 18630:18630 -d --name streamsets-dc streamsets/datacollector

The default login is: admin / admin.

Detailed Usage

You can specify a custom configs by mounting them as a volume to /etc/sdc or /etc/sdc/<configuration file>
Configuration properties in sdc.properties and dpm.properties can also be overridden at runtime by specifying them env vars prefixed with SDC_CONF or DPM_CONF
- For example http.port would be set as SDC_CONF_HTTP_PORT=12345
You should at a minimum specify a data volume for the data directory unless running as a stateless service integrated with StreamSets Control Hub. The default configured location for SDC_DATA is /data. You can override this location by passing a different value to the environment variable SDC_DATA.
You can also specify your own explicit port mappings, or arguments to the streamsets command.
When building the image yourself, files or directories placed in the "resources" directory at the project root will be copied to the image's SDC_RESOURCES directory.
When building the image yourself, files or directories placed in the "sdc-extras" directory at the project root will be copied to the image's STREAMSETS_LIBRARIES_EXTRA_DIR. See the Dockerfile for details

For example to run with a customized sdc.properties file, a local filsystem path to store pipelines, and statically map the default UI port you could use the following:

docker run --restart on-failure -v $PWD/sdc.properties:/etc/sdc/sdc.properties:ro -v $PWD/sdc-data:/data:rw -p 18630:18630 -d streamsets/datacollector

Creating Data Volumes

To create a dedicated data volume for the pipeline store issue the following command:

docker volume create --name sdc-data

You can then use the -v (volume) argument to mount it when you start the data collector.

docker run -v sdc-data:/data -P -d streamsets/datacollector

Note: There are two different methods for managing data in Docker. The above is using data volumes which are empty when created. You can also use data containers which are derived from an image. These are useful when you want to modify and persist a path starting with existing files from a base container, such as for configuration files. We'll use both in the example below. See Manage data in containers for more detailed documentation.

Pre-configuring Data Collector

Option 1 - Deriving a new image (Recommended)

The simplest and recommended way is to derive your own custom image.

For example, create a new file named Dockerfile with the following contents:

ARG SDC_VERSION=3.9.1
FROM streamsets/datacollector:${SDC_VERSION}

ARG SDC_LIBS
RUN "${SDC_DIST}/bin/streamsets" stagelibs -install="${SDC_LIBS}"

To create a derived image that includes the Jython stage library for SDC version 3.9.1, you can run the following command:

docker build -t mycompany/datacollector:3.9.1 --build-arg SDC_VERSION=3.9.1 --build-arg SDC_LIBS=streamsets-datacollector-jython_2_7-lib .

Option 2 - Volumes

First we create a data container for our configuration. We'll call ours sdc-conf

docker create -v /etc/sdc --name sdc-conf streamsets/datacollector docker run --rm -it --volumes-from sdc-conf ubuntu bash

Tip: You can substitute ubuntu for your favorite base image. This is only a temporary container for editing the base configuration files.

Edit the configuration of SDC to your liking by modifying the files in /etc/sdc

You can choose to create separate data containers using the above procedure for $SDC_DATA (/data) and other locations, or you can add all of the volumes to the same container. For multiple volumes in a single data container you could use the following syntax:

docker create -v /etc/sdc -v /data -v --name sdc-volumes streamsets/datacollector

If you find it easier to edit the configuration files locally you can, instead of starting the temporary container above, use the docker cp command to copy the configuration files back and forth from the data container.

To install stage libs using the CLI or Package Manager UI you'll need to create a volume for the stage libs directory. It's also recommended to use a volume for the data directory at a minimum.

docker volume create --name sdc-stagelibs (If you didn't create a data container for /data then run the command below) docker volume create --name sdc-data

The volume needs to then be mounted to the correct directory when launching the container. The example below is for Data Collector version .1.

docker run --name sdc -d -v sdc-stagelibs:/opt/streamsets-datacollector-3.9.1/streamsets-libs -v sdc-data:/data -P streamsets/datacollector dc -verbose

To get a list of available libs you could do:

docker run --rm streamsets/datacollector:3.9.1 stagelibs -list

For example, to install the JDBC lib into the sdc-stagelibs volume you created above, you would run:

docker run --rm -v sdc-stagelibs:/opt/streamsets-datacollector-3.9.1/streamsets-libs streamsets/datacollector:3.9.1 stagelibs -install=streamsets-datacollector-jdbc-lib
