StreamPipes CLI - The Developer's Favorite

The StreamPipes command-line interface (CLI) is focused on developers in order to provide an easy entrypoint to set up a suitable dev environment, either planning on developing

• new extensions such as connect adapters, processors, sinks or,
• new core features for backend and ui.

Current version: 0.97.0-SNAPSHOT

TL;DR

streampipes env --list
[INFO] Available StreamPipes environment templates:
pipeline-element
...
streampipes env --set pipeline-element
streampipes up -d

NOTE: use ./installer/cli/streampipes if you haven't add it to the PATH and sourced it (see section "Run streampipes from anywhere?").

Prerequisite

The CLI is basically a wrapper around multiple docker and docker-compose commands plus some additional sugar.

• Docker >= 17.06.0
• Docker-Compose >= 1.26.0 (Compose file format: 3.4)
• Google Chrome (recommended), Mozilla Firefox, Microsoft Edge
• For Windows Developer: GitBash only

Tested on: (macOS, Linux, Windows)

NOTE: If you're using Windows the CLI only works in combination with GitBash - CMD, PowerShell won't work.

CLI commands overview

StreamPipes CLI - Manage your StreamPipes environment with ease

Usage: streampipes COMMAND [OPTIONS]

Options:

  --version, -v   show version

Commands:
  add         Add new StreamPipes service (e.g., adapter, processor, sink)
  clean       Remove StreamPipes data volumes, dangling images and network
  down        Stop and remove StreamPipes containers

  logs        Get container logs for specific container
  ps          List all StreamPipes container for running environment
  pull        Download latest images from Dockerhub
  restart     Restart StreamPipes container
  start       Start StreamPipes container
  stop        Stop StreamPipes container
  up          Create and start StreamPipes container environment

Run 'streampipes COMMAND --help' for more info on a command.

Usage: Along dev life-cycle

List available environment templates.

streampipes env --list

Inspect services in an available environment to know what kind of services it is composed of.

streampipes env --inspect pipeline-element

Set environment, e.g. pipeline-element, if you want to write a new pipeline element.

streampipes env --set pipeline-element

Start environment ( default: dev mode). Here the service definition in the selected environment is used to start the multi-container landscape.

NOTE: dev mode is enabled by default since we rely on open ports to core service such as couchdb, kafka etc. to reach from the IDE when developing. If you don't want to map ports (except the UI port), then use the --no-ports flag.

streampipes up -d
# start in production mode with unmapped ports
# streampipes up -d --no-ports

Now you're good to go to write your new pipeline element 🎉 🎉 🎉

HINT for extensions: Use our Maven archetypes to setup a project skeleton and use your IDE of choice for development. However, we do recommend using IntelliJ.

HINT for core: To work on backend or ui features you need to set the template to backend and clone the core repository streampipes - check the prerequisites there for more information.

Stop environment and remove docker container

streampipes down
# want to also clean docker data volumes when stopping the environment?
# streampipes down -v

Additionally, useful commands

Start individual services only? We got you! You chose a template that suits your needs and now you only want to start individual services from it, e.g. only Kafka and CouchDB.

NOTE: the service names need to be present and match your current .spenv environment.

streampipes up -d kafka couchdb

Get current environment (if previously set using streampipes env --set <environment>).

streampipes env

List containers of environment.

streampipes ps
# include also stopped container
streampieps ps --all

Get logs of specific service and use optional --follow flag to stay attached to the logs.

streampipes logs --follow backend

Update all services of current environment

streampipes pull

Stop existing StreamPipes containers

streampipes stop extensions-all-jvm

Start existing StreamPipes containers

streampipes start extensions-all-jvm

Restart existing services

# restart backend couchdb container
streampipes restart backend couchdb
# restart existing services by removing and recreating container instance
streampipes restart --force-create extensions-all-jvm

Clean your system and remove created StreamPipes Docker volumes, StreamPipes docker network and dangling StreamPipes images of old image layers.

streampipes clean
# remove volumes, network and dangling images
# streampipes clean --volumes

Add newly developed StreamPipes Pipeline Elements to service catalog

As you develop new pipeline elements, e.g., adapters, processors or sinks, you might want to add them to your existing environment. Adding these components requires minimal effort. We can simply use streampipes add command to populate relevant Docker Compose files under the StreamPipes working directory (deploy/standalone/).

NOTE: This requires your own pipeline elements to be already containerized and accessible to pull, e.g., from a public Docker repository such as DockerHub. If you use a private repository make sure your local Docker Daemon has access to it.

# check out streampipes add --help for more options
# add new pipeline element to catalog, here my-processor
streampipes add my-processor

# add new pipeline element with custom image and ports
streampipes add my-processor --image myrepo/myprocessor:0.68.0 --ports 8090:8090 --ports 8091:8091

# [Optional] add new pipeline element and persistently store service in environment (here: lite) and activate service in current environment (.spenv)
streampipes add my-processor --store lite --activate

In general, this creates necessary Docker Compose files in the local service catalog:

cli/deploy/standalone/my-processor
├── docker-compose.dev.yml
└── docker-compose.yml

If you activated the pipeline element while adding via the flag --activate, you can directly start you new pipeline element using the following command. Otherwise, you will have to manually add it at a later point.

NOTE: The service name must match the directory name under deploy/standalone/<service_name>

streampipes up -d my-processor

Modify/Create an environment template

As of now, this step has to be done manually. All environments are located in environments/.

├── adapter               # developing a new connect adapter
├── backend               # developing core backend features
├── basic                 # wanna run core, UI, connect etc from the IDE?
├── full                  # full version containing more pipeline elements
├── lite                  # few pipeline elements, less memory
├── pipeline-element      # developing new pipeline-elements
└── ui                    # developing UI features

Modifying an existing environment template. To modify an existing template, you can simply add a <YOUR_NEW_SERVICE> to the template.

NOTE: You need to make sure, that the service your are adding exists in deploy/standalone/service/<YOUR_NEW_SERVICE>. If your're adding a completely new service take a look at existing ones, create a new service directory and include a docker-compose.yml and docker-compose.dev.yml file.

[environment:backend]
activemq
kafka
...
<YOUR_NEW_SERVICE>

Creating a new environment template. To create a new environment template, place a new file environments/<YOUR_NEW_ENVIRONMENT> in the template directory. Open the file and use the following schema.

IMPORTANT: Please make sure to have [environment:<YOUR_NEW_ENVIRONMENT>] header in the first line of your new template matching the name of the file. Make sure to use small caps letters (lowercase) only.

[environment:<YOUR_NEW_ENVIRONMENT>]
<SERVICE_1>
<SERVICE_2>
...
