Rebuilt practically every day with potential changes from upstream that we cannotĪlways test fast enough. Improved reliability and stability - The existing legacy convenience images are Using these new images will lead to faster image downloads when a build starts, and a higher likelihood that the image is already cached on the host. Here are some of the highlights:įaster spin-up time - In Docker terminology, these next-gen images will generally have fewer and smaller layers. The next-generation convenience images in this section were built from the ground up with CI, efficiency, and determinism in mind.

Refer to the Tutorials for examples of using pre-built CircleCI Docker Images in a demo application. Please follow the convenience-images tag onĭiscuss to be notified in advance of scheduled maintenance.

Otherwise improve functionality, and these changes can sometimes affect Note: CircleCI occasionally makes scheduled changes to images to fix bugs or All CircleCI pre-built images are available for browsing on Docker Hub.

Visit the circleci-images GitHub repo for the source code for the legacy CircleCI Docker images.

Visit the Developer Hub for links to all the repositories for each next-gen image.

If you would like to directly search for an image, you can browse CircleCI Docker images in the following locations: Please note that we advise using the next-generation images convenience images rather than legacy images (as explained below). This document will provide an overview of best practices when using a convenience image. Typically extensions of official Docker images and include tools especially The advantage of this method vs running KSQL Server headless with a queries file passed to it is that you can still interact with KSQL this way, but can pre-build the environment to a certain state.This document provides information about pre-built CircleCI images and a listing by language, service type, and tags in the following sections:įor convenience, CircleCI maintains several Docker images.

confluent-hub install -no-prompt confluentinc/kafka-connect-gcs:5.0.0 You could combine both this and the technique above if you wanted to install a custom connector plugin before launching Kafka Connect, e.g. You could build this into the Docker Compose but it feels a bit yucky. The actual script to configure the connector is a curl call in a separate file. Sleep infinity is necessary, because we’ve sent the /etc/confluent/docker/run process to a background thread ( &) and so the container will exit if the main command finishes. In the command section, $ are replaced with $$ to avoid the error Invalid interpolation format for 'command' option While [ $$(curl -s -o /dev/null -w % ' (waiting for 200)'Įcho -e ' - +> Creating Kafka Connect Elasticsearch sink' Kafka-connect: image: confluentinc/cp-kafka-connect:5.1.2 environment: CONNECT_REST_PORT: 18083 CONNECT_REST_ADVERTISED_HOST_NAME: 'kafka-connect' volumes: - $PWD/scripts:/scripts command: - bash -c - |Įcho 'Waiting for Kafka Connect to start listening on kafka-connect ⏳' Kafka Connect, KSQL Server, etc) you can use this bash snippet to force a script to wait before continuing execution of something that requires the service to actually be ready and available: For a service that exposes an HTTP endpoint (e.g. So Docker Compose’s depends_on dependencies don’t do everything we need here. Often a container will be ‘up’ before it’s actually up. Wait for an HTTP endpoint to be available So, here’s a collection of tricks I use with Docker and Docker Compose that might be useful, particularly for those working with Apache Kafka and Confluent Platform. Tear it down, run it again, without worrying that somewhere a local config changed and will break things. With them I can build self-contained environments for tutorials, demos, conference talks etc. Docker, and Docker Compose, are one of my key tools of the trade.
