Frontend stopped connecting to recorder.

I run owntracks recorder and frontend in swarm. After the latest recorder upgrade (version 0.8.8), the frontend stopped working properly. It is throwing:

I hope you can point me to the right direction in order to fix this issue…

Oh, it is just easier for me to test different things.

ENTRYPOINT starts the container with parameters that cannot be overridden with CLI parameters. CMD allows to do so.

In other words, when you specify:

ENTRYPOINT=/usr/bin/my-script.sh

then you cannot start your container with different parameter/script for example:

docker run -it my-docker-image /usr/bin/different-script.sh

The above example will start your container with /usr/bin/my-script.sh regardless what you specify as a starting parameter. In fact /usr/bin/different-script.sh will be interpreted as a parameter for your entrypoint.

When you use

CMD=["/usr/bin/my-script.sh"]

instead, you can override the starting point, so the above command will start your container with /usr/bin/different-script.sh.

When you specify both ENTRYPOINT and CMD, then whatever you put into the CMD becomes a parameter for your entrypoint. For example:

ENTRYPOINT=/usr/bin/my-script.sh
CMD=["parameter1", "parameter2"]

will be interpreted as:

/usr/bin/my-script.sh parameter1 parameter2

and you can override parameters with:

docker run -it my-docker-image parameter3

which will be corresponding to:

/usr/bin/my-script.sh parameter3

I hope this makes sense.

In my Dockerfile it can easily be moved to ENTRYPOINT. No problems with that 😉

Thank you.
