When working on a remote High-Performance Computing (HPC) cluster or a cloud server, accessing development tools locally can be challenging. One effective approach is to use an SSH tunnel to securely access a galaxy server-a web platform as if it were running on your local machine. Processes in Computer

info
  • Replace with your host and port for ssh
  • Run any web on specific port, then forward this web service via ssh to access at your local machine
  • Require to install docker. For more details on, please visit galaxy docker

Why Use SSH Tunneling?​

SSH tunneling allows you to securely forward ports from a remote server to your local system. This is useful for accessing services that are running on the remote machine without exposing them to the internet.

Login to your remote server​

ssh river@platform.riverxdata.com

Run a web service​

It can be accessed at localhost 8080 Run galaxy server- a web platform for bioinformatics:

docker run -d -p 8080:80 \
    -v ./galaxy_storage/:/export/ \
    quay.io/bgruening/galaxy

The web is now available on a remote system on the port 8080, docker bind the port of the web is running at 80 on the container.

Test the web service​

Test the web service at 8080

curl localhost -p 8080

Processes in Computer

Now you can access the galaxy at your local computer via ssh. With the local machine will access this network at port 8081 which is remoted from 8080 of the platform.riverxdata.com

ssh -N -L 8081:localhost:8080 platform.riverxdata.com
