mount error

[zhoushengsheng-droid]

Hi, I recently want to mount a network disk into the container of this project. I modified KVM Py file adds this parameter -- privileged. But after adding this parameter. My JNLP file cannot be opened. How to modify it？

[IngoMeyer441]

Hey,
for mounting, it is probably better to use the --mount or --volume option of the Docker command. This is the link to the documentation for an NFS mount: https://docs.docker.com/storage/volumes/#create-a-service-which-creates-an-nfs-volume. There are also other examples for network mounts.

Do you get an error message? You can run nojava-ipmi-kvm with the --debug flag to get more detailed output.

[zhoushengsheng-droid]

Not container error. Java in the container cannot open the JNLP file I obtained. If this parameter is not added, it can be accessed normally

[IngoMeyer441]

Does it work when you replace --privilged with a --mount parameter? For direct mounts you don't need the --privileged flag.

I changed KVM directly Is the PY file OK? Will it affect other uses？

[IngoMeyer441]

I think it is ok to change the Python file to test the mounting. It would be better to add a command line option to nojava-ipmi-kvm to make it available in general.

Hi, I have a new question. Nojava cannot be deleted continuously by holding down the backspace key. You can only use the backspace key to click continuously to delete. Can this be optimized?

[IngoMeyer441]

Thanks for pointing me to this issue. This should be fixed in commit f7a6046 and version v0.9.2. Please upgrade to the latest version to get the patch.

Hi. I have another problem. If I want to use the mount function in VNC, I need another JNLP file of VM. Can nojava download one more JNLP file specified by me internally and let me open it?

[IngoMeyer441]

Couldn't you use another download link in the configuration for that case?

[zhoushengsheng-droid]

The main reason is that the supervisor in the image configuration has only one JNLP file open. Will he download two JNLP files and open them?

[IngoMeyer441]

So, you would like to set a list of JNLP files in the central configuration file and then all the given JNLP files should be started in parallel?
Sorry for all the questions, but I try to understand how this feature should work and why it is needed. Maybe there is another way of solving your problem.

[zhoushengsheng-droid]

VM  on yes KVM on yes The attached image of this server is divided into two parts. I mean, can the program just define one more download address, and then it can download KVM files of two addresses and pull them into the container, so as to open the two JNLP files at the same time to complete the acquisition of this server.

[IngoMeyer441]

The images are not visible in the GitHub issue tracker.

It would be possible to load multiple JNLP files, but this needs quite a lot of code changes and I have no system to test this. But I always welcome code contributions. I think these changes are necessary:

• The config file needs to store either a string or a list as download endpoint. Since the config file is parsed by PyYaml, it would create either a Python string or list which is passed to the JavaHostConfig class and needs to be updated to accept a list type.
• The download_endpoint attribute is read in the kvm.py module and then is passed to get_java_viewer.py in the Docker container.
• The get_java_viewer.py needs to be updated to accept a list for the download endpoint and then needs to handle multiple download urls in the get_java_viewer function.
• The supervisord configs files (for example this one) need to be updated to allow to start more than one JNLP file. Currently, this file is static. It probably needs to be generated dynamically to add as many javaws processes as needed.

HI In other words, I need to change the "KVM. Py" file, and then I need to change the two modules "get_java_viewer. Py" in the image to complete what I said, right. Can you tell me in detail how "get_java_viewer. Py" and "KVM. Py" present this effect by command in the system. I need to know that he manually operates the manual process to make a code upgrade design. In this way, it is better to update the Python code. THANKS

[IngoMeyer441]

The code makes a login to the KVM web page, downloads the viewer and passes it to /usr/bin/javaws. The relevant code lines (and statements or commands) are referenced in my previous post.

Maybe the links are not shown in the GitHub mail. But they are visible in the GitHub comment box: #13 (comment)

[zhoushengsheng-droid]

Sorry, I'll delete it

[zhoushengsheng-droid]

Hi, I can successfully mount and attach the image by adding these two parameters. "-- CAP add = sys_admin", "-- CAP add = dac_read_search". Of course, if you add modules to nojava later, you'd better take another method.
