This docker image attempts to simplify the setup required by Jepsen. It is intended to be used by a CI tool or anyone with Docker who wants to try Jepsen themselves.
It contains all the jepsen dependencies and code. It uses Docker Compose to spin up the five containers used by Jepsen.
Assuming you have docker-compose set up already, run:
bin/up
bin/console
... which will drop you into a console on the Jepsen control node.
Your DB nodes are n1
, n2
, n3
, n4
, and n5
. You can open as many shells
as you like using bin/console
. If your test includes a web server (try lein run serve
on the control node, in your test directory), you can open it
locally by running using bin/web
. This can be a handy way to browse test
results.
If you need to log into a DB node (e.g. to debug a test), you can ssh n1
(or n2, n3, ...) from inside the control node, or:
docker exec -it jepsen-n1 bash
During development, it's convenient to run with --dev
option, which mounts $JEPSEN_ROOT
dir as /jepsen
on Jepsen control container.
Run ./up.sh --help
for more info.
