Thank you for your report @jmwilkinson
ZOO_MY_ID works just fine out of the box.
$ docker run -it --rm -e ZOO_MY_ID=1 zookeeper

From what I see in your logs it tries to find myid in /var/lib/zookeeper which probably means you use a custom config file. But the value from ZOO_MY_ID is written into $ZOO_DATA_DIR/myid by default. Where ZOO_DATA_DIR equals /data by default.
You can probably solve the issue in three different ways:
- Add
dataDir=/datainto yourzoo.cfgso thatZOO_MY_IDwill work (recommended). - Set
ZOO_DATA_DIRenv var to/var/lib/zookeeper. - Put
myidfile into/var/lib/zookeeper.

Hey @jmwilkinson was the issue solved somehow?

Hey @31z4
Sorry for the delayed response.
I already had the dataDir specified in my config (pointing to a non-default location). I solved the problem by writing the id directly to the myid file, and then starting zookeeper.

Alright! So I'm closing this.

Ok. To be clear, this is still a bug somewhere- though perhaps with zookeeper and not the docker build.
