+# Topotests in Docker
+
+## Quickstart
+
+If you have Docker installed, you can run the topotests in Docker.
+The easiest way to do this, is to use the make targets from this
+repository.
+
+Your current user needs to have access to the Docker daemon. Alternatively
+you can run these commands as root.
+
+```console
+make topotests
+```
+
+This command will pull the most recent topotests image from dockerhub, compile FRR inside
+of it, and run the topotests.
+
+## Advanced Usage
+
+Internally, the topotests make target uses a shell script to pull the image and spawn the docker
+container.
+
+There are several environment variables which can be used to modify the behavior
+of the script, these can be listed by calling it with `-h`:
+
+```console
+./tests/topotests/docker/frr-topotests.sh -h
+```
+
+For example, a volume is used to cache build artifacts between multiple runs
+of the image. If you need to force a complete recompile, you can set `TOPOTEST_CLEAN`:
+
+```console
+TOPOTEST_CLEAN=1 ./tests/topotests/docker/frr-topotests.sh
+```
+
+By default, `frr-topotests.sh` will build frr and run pytest. If you append
+arguments and the first one starts with `/` or `./`, they will replace the call to
+pytest. If the appended arguments do not match this patttern, they will be provided to
+pytest as arguments.
+
+So, to run a specific test with more verbose logging:
+
+```console
+./tests/topotests/docker/frr-topotests.sh -vv -s all-protocol-startup/test_all_protocol_startup.py
+```
+
+And to compile FRR but drop into a shell instead of running pytest:
+
+```console
+./tests/topotests/docker/frr-topotests.sh /bin/bash
+```
+
+## Development
+
+The docker image just includes all the components to run the topotests, but not the topotests
+themselves. So if you just want to write tests and don't want to make changes to the environment
+provided by the docker image. You don't need to build your own docker image if you do not want to.
+
+When developing new tests, there is one caveat though: The startup script of the container will
+run a `git-clean` on its copy of the FRR tree to avoid any pollution of the container with build
+artefacts from the host. This will also result in your newly written tests being unavailable in the
+container unless at least added to the index with `git-add`.
+
+If you do want to test changes to the docker image, you can locally build the image and run the tests
+without pulling from the registry using the following commands:
+
+```console
+make topotests-build
+TOPOTEST_PULL=0 make topotests
+```

+ TOPOTEST_BUILDCACHE Docker volume used for caching multiple FRR builds
+ over container runs. By default a
+ \`topotest-buildcache\` volume will be created for
+ that purpose.
+
+ TOPOTEST_CLEAN Clean all previous build artifacts prior to
+ building. Disabled by default, set to 1 to enable.
+
+ TOPOTEST_DOC Build the documentation associated with FRR.
+ Disabled by default, set to 1 to enable.
+
+ TOPOTEST_FRR If set, don't test the FRR in the current working
+ directory, but the one at the given path.
+
+ TOPOTEST_LOGS If set, don't use \`/tmp/topotest_logs\` directory
+ but use the provided path instead.
+
+ TOPOTEST_OPTIONS These options are appended to the docker-run
+ command for starting the tests.
+
+ TOPOTEST_PULL If set to 0, don't try to pull the most recent
+ version of the docker image from dockerhub.

+Welcome to the topotests container.
+
+Here are some useful tips:
+* After changing the FRR/Topotests sources, you may rebuild them
+ using the command `compile_frr.sh`. The build command has the
+ following environment variables:
+ - TOPOTEST_CLEAN: whether we should distclean or not (disabled by default)
+ - TOPOTEST_VERBOSE: show build messages (enabled by default)
+ - TOPOTEST_DOC: whether we should build docs or not (disabled by default)
+ - TOPOTEST_SANITIZER: whether we should use the address sanitizer (enabled by default)
+
+ Usage example: env TOPOTEST_CLEAN=1 compile_frr.sh
+
+* The topotests log directory can be found on your host machine on
+ `/tmp/topotests_logs`.
