Accessing the inside of a warden container

This document explains how to get inside a warden container that runs a given application.

The following is assumed:

• jq is installed on all of the machines we will be using (it's as simple as apt-get install jq if you don't have it).
• alamakota is the administrator password.
• butla-rest-demo.example.com is the url the application is using.

Jumpbox

Connect to the jumpbox and change the current directory to ~/workspace/deployments/cf-boshworkspace.

Gorouter IP

Find the IP address of the machine with the gorouter: bosh vms | awk -F\| '/api/{ print $5 }'.

If there are multiple, either one is fine. For this guide, I will assume 10.10.3.7.

Runner IP

Get the IP address of the runner that hosts the application: curl -s http://router:alamakota@10.10.3.7:8080/routes | jq '.["butla-rest-demo.example.com"][]' | sed 's/:.*"/"/'.

Remember to replace alamakota with the admin password, butla-rest-demo.example.com with the application URL and 10.10.3.7 with the API address from the Gorouter IP step!

Runner name

Get the name of the runner that has the IP address we got in the previous step: bosh vms | awk -F\| '/10.10.3.54/{ print $2 }'.

Remember to replace 10.10.3.54 with the address from the Runner name step!

Runner SSH

SSH to the runner machine with bosh ssh runner_z1/3.

Remember to replace runner_z1/3 with the name you got from the Runner name step!

Get container ID

Get the container ID running sudo jq '.instances[] | select(.application_uris[0] == "butla-rest-demo.example.com") | .warden_handle' /var/vcap/data/dea_next/db/instances.json.

Remember to replace butla-rest-demo.example.com with your application URL!

Jump to container

Jump to the app container with the following command: /var/vcap/packages/warden/warden/src/wsh/wsh --user vcap --socket /var/vcap/data/warden/depot/18ekh2ovjh5/run/wshd.sock.

Remember to replace 18ekh2ovjh5 with the output of the Get container ID step!

Congratulations! You are in the container!
