Unable to start maxwell with barebone options, issue with server_id

[tankchintan]

I am trying to use the quick start guide's example of starting maxwell service via docker but I am having troubles with server_id.

Here is output of running 2 commands.

➜  maxwell docker run -it --rm osheroff/maxwell bin/maxwell --user=maxwell --password=maxwell --host=W.X.Y.Z  --producer=stdout
com.zendesk.maxwell.MaxwellCompatibilityError: server_id is '0'.  Maxwell will not function without a server_id being set.
	at com.zendesk.maxwell.MaxwellMysqlStatus.ensureServerIDIsSet(MaxwellMysqlStatus.java:50)

	at com.zendesk.maxwell.Maxwell.main(Maxwell.java:199)
21:27:21,392 INFO  Maxwell - starting shutdown

So I decided to add a server_id, but still no luck.

➜  maxwell docker run -it --rm osheroff/maxwell bin/maxwell --user=maxwell --password=maxwell --host=W.X.Y.Z --server_id=1 --producer=stdout

Found the issue.

Issue was that server_id is actually fetched from the mysql server & not from any configuration passed to maxwell. Since my local mysql was not setup to have any server_id it was being set to 0.

To resolve this, I updated my my.cnf file to have server_id=1 & restarted mysql. Now its good to go.
