Building an Envoy Docker image

The following steps guide you through building your own Envoy binary, and putting that in a clean Ubuntu container.

Step 1: Build Envoy

Using envoyproxy/envoy-build you will compile Envoy. This image has all software needed to build Envoy. From your Envoy directory:

  1. $ pwd
  2. src/envoy
  3. $ ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.release'

That command will take some time to run because it is compiling an Envoy binary and running tests.

For more information on building and different build targets, please refer to ci/README.md.

Step 2: Build image with only envoy binary

In this step we’ll build an image that only has the Envoy binary, and none of the software used to build it.:

  1. $ pwd
  2. src/envoy/
  3. $ docker build -f ci/Dockerfile-envoy-image -t envoy .

Now you can use this envoy image to build the any of the sandboxes if you change the FROM line in any Dockerfile.

This will be particularly useful if you are interested in modifying Envoy, and testing your changes.
