Trying to setup a docker test env.

[GadgetChris]

At https://github.com/ZoneMinder/zoneminder/wiki/Docker it describes the setup of a dev environment in docker.
I'm trying to follow it, and it's complaining about :

Code: Select all

ERROR: failed to solve: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount3288439779/Dockerfile: no such file or directory 

The same happens when trying to use my own branch.

Clearly this is my first attempt setting up a dev env for ZM.


I see there is a separate project https://github.com/ZoneMinder/zmdockerf ... Dockerfile
I'm not sure how to marry the two together to be able to run my code

[GadgetChris]

OK, I have test docker running from source zoneminderhq/zoneminder:latest-ubuntu18.04.
How can I run my local code?
Do I have to do a cmake? what are the options?

Seems the Dockerfile is missing.

Thank you, GadgetChris

It's unable to connect to the ubuntu repos. In my experience, this is usually a DNS issue, but it seems to have the IP address so maybe it's just a routing issue. If you run the container and have it idle at the end, can you login to the container and manually connect to the repos with wget or ping? Maybe the repo URL has changed. Maybe it's a firewall issue between docker and your computer.

The situation with Docker and ZM, is the following:
1) the devs aren't really working on it, it's only been from volunteers who have made some images. So you are mostly on your own
2) this should be posted in the docker forum
3) this looks like a fundamental docker troubleshooting issue that is not related to ZM. You might want to familiarize yourself with Docker a bit more. I've recommended the book by Adrian Mouat a couple times (although it's older, but probably still relevant).

I doubt anything with ZM and docker is difficult, but it's a timesink and so far people just haven't had the bandwidth to work on it. Finally, you should look through the docker forum to see what else is available. From my memory you should be able to find a working ZM configuration, but might have trouble finding one with ZMES and MLAPI.
