You can use SSH to inspect how your app is operating, transfer files via SCP, or interact directly with your bound services. More information about one-off tasks.
You can get a shell via the
command, which lets you securely log in to an application instance where you can
perform debugging, environment inspection, and other tasks.
Your application environment is not completely set up when you log in. You’ll probably need to configure your session to match your application’s environment in order to debug your application.
You can interact directly with the services bound to your application via port forwarding (described under “Configure Your SSH Tunnel”). This allows you to access those services using native clients on your local machine. The Service Connect plugin makes this even easier.
cf sshuses port 2222. If your network blocks port 2222, you may receive an error message such as

pythonwithin an SSH session results in
ImportError: No module named site.
- To resolve this, configure your SSH session environment with these two commands:
export DEPS_DIR=/home/vcap/deps for f in /home/vcap/profile.d/*.sh; do source "$f"; done
How to disable SSH access
SSH access is enabled by default. Space Developers can disable SSH access to individual applications, and Space Managers can disable SSH access to all apps running within a space. See Enabling and Disabling SSH Access for the commands.
SSH version information
Application containers use the SSH-2.0 protocol. The SSH service uses the Cloud Foundry SSH implementation. For more on how Cloud Foundry implements SSH, refer to Cloud Foundry’s documentation on Understanding Application SSH.
