[doc] The example function yaml could not be run

[imaffe]

In the function mesh documentation, there is a step to run kubectl apply -f config/samples/compute_v1alpha1_function.yaml

And this yaml requires some extra setup, such as upload the function jar to pulsar storage or pack into the running image. The function jar location refers to a local test name as well.

One thing we can do is to create a demo image containing the basic jar and use the image in compute_v1alpha1_function.yaml.

There is a sample image folder to create images for running jars. Need to investigate if the samples are being used and updated now~

Looks like the best way would be to create a public docker registry and use the docker image to run the documentation command.

Another way is we change the example YAML to use a full pulsar image, like pulsar-all, and set the java.jar to /pulsar/examples/...jar, remove java.jarLocation as well.

I encountered mkdir: cannot create directory '/pulsar/conf/java-log/': Permission denied when using the pulsar-all image, maybe need to run as root as well.

what's the tag of the pulsar-all image you are using?

@tpiperatgod 2.9.2.23

@imaffe pulsar 2.9 is still in root image, and the /pulsar directory is owned by root, so if you want to use pulsar-all as the runner image, you will need to set spec.pod.securityContext.runAsUser: 0 to make the container run with the correct user.
