how to build cmk docker image.

Hi guys, how to build cmk docker image ? from the code path -/CODE/Dockerfile? thanks.

hey @shunianyin, you can run "make" from the root CMK directory which will build the docker image.

but I get an Error when I building the docker image.
The Error like
"ERROR: InvocationError: '/cmk/.tox/integration/bin/py.test -v --cov --cov-report=annotate --cov-append tests/integration'".

Could you let us know what version of CMK you are using and what version of K8s?
Also if there is more to the error logs could you attach those as well.

OK, i want to know whether the docker image of CMK must be bulit in the k8s. But now K8s is not installed in host environment(docker 17.12.1-ce、Python 3.4.6 、cmk 1.3.0), which may cause the above problem.

I also have another question to ask you. Does CMK support allocating CPU with the corresponding policies when i create Pod container which uses a new option (the num of cpus)? thanks .

@lmdaly
I have now successfully bulit the docker image of CMK.
But configuration directory initialization failed through the subcommand of cmk init.
Example:
$ docker run -it cmk:v1.3.0 --volume=/etc/cmk:/etc/cmk:rw
cmk init --conf-dir=/etc/cmk --num-exclusive-cores=4 --num-shared-cores=1
After executing the above command,the corresponding container did not start up.
How to correctly use the cmk command-line tool?
thanks.

Hey, there is a mistake in the documentation for the docker runs for CMK.

Here is the correct command to run the init command with CMK -
docker run -it --volume=/etc/cmk:/etc/cmk:rw --env CMK_PROC_FS=/proc cmk:v1.3.0 init --conf-dir=/etc/cmk --num-exclusive-cores=4 --num-shared-cores=1
