Hi,

glad to hear that you were able to progress.

By the way, you can modify the URL to be used by setting an envrionment variable before running the application, e.g. for a bash shell: "export TRACE_SERVER_URL=https://127.0.0.1/tsp/api", just replace the https://127.0.0.1 with the corresponding address. Gitpod is doing that for example.

Bernd

Found the issue! The client expected to find the server on localhost:8080, which I thought was correct to begin with as I believed the request would be issued from within the container. On second thought I guess the are issued from the browser so by changing from localhost:8080 to website:8080 and adding a port mapping on 8080:8080 the requests are now routed correctly to the server within the container 😊


I am still a little confused why I can curl localhost:8080 from the host, while it is not possible for the browser? 


Anyways, problem solved!

Hello again,

I am struggling with making my docker environment work with Theia and the Trace server. I have made my own docker file which includes Java, NodeJS and Yarn. I am able to start both the server and the client and I can load the server with traces and I can curl both the server and client from within the container and the host. I can also reach the client from outside the host so that works fine. 

The issue is that the client does not seem to be able to communicate properly with the server. If I start the server manually the client throws an exception on the port being busy. I believe that is because the client attempts to start the server itself, however, this does not happen outside the container so not sure why it doesn't connect to the already started server. 

If I let the client start the server it does not seem to be able to fetch the experiments, but I am able to retrieve them with the tsp-python-client. It just opens the filesystem. 

I believe the core issue is that I am missing some packages in my Dockerfile, because when I build the client there are several errors which does not happen on the host or my local computer. 

Any thoughts on what I might be missing? I see that there is a gitpod.dockerfile and a .gitpod.yml in the client repo, but I am not sure how to configure it so it will use my local trace server loaded with my jpftraces. 

Started to learn Docker yesterday so I am a little confused on how it works 😊 

Appreciate any help!

Best regards
Johan

Just solved it!


It was possible to add --hostname and --port as arguments 😊

Hello,



Im making an experiment for my master thesis and I would like to expose my local theia client so instead of running on localhost I would like to bind it to the host IP, so some students who will participate in the experiment can try out the trace visualizer.


I have located some settings in .vscode where I change URL for chrome and firebox. By default it is localhost:3000. However, this does not seem to give any effect, I can still curl localhost:3000 after changing and rebuilding.


Any ideas of how to solve this? 


Best regards

Johan
