At **Port** setting of **Create a new workspace** page, you can expose a server application running in a VESSL workspace instance on a configured port.
Before editing your port settings, you should stop your workspace.
# Running a server application
You can run a simple server application like the following Python file server.
```
vessl@workspace-twyiu9wvy55d-0:~$ ls
mnist
vessl@workspace-twyiu9wvy55d-0:~$ ls mnist
test.csv train.csv
vessl@workspace-twyiu9wvy55d-0:~$ python -m http.server 8080
Serving HTTP on 0.0.0.0 port 8080 (http://0.0.0.0:8080/) ...
```
You can access the running server application by clicking the port number at **Metadata**.
