Troubleshooting using swimlane-tools pod

the swimlane application container images such as swimlane web, swimlane tasks, and swimlane api by design are lightweight and do not include the basic utilities such as curl, telnet, ping, nslookup, etc the reduced image size helps speed up the building and deploying of the containers to make troubleshooting easier, the swimlane platform installer includes a swimlane tools container that can be used for diagnosing the most common issues, especially for air gapped/offline installs this would include, for example, tools like telnet, nslookup, curl, netcat, mtr, tcptraceroute (to test network connectivity), ldapsearch (for ldap issues), mongo client, and other useful utilities accessing the swimlane tools container there are few ways to execute into the container here are two options kubectl n \<swimlane namespace> get pods kubectl exec it \<swimlane tools pod> /bin/bash available tools the container includes the following tools debian linux apt tools curl dnsutils htop iftop iotop iputils ping jq ldap utils mtr nano net tools netcat ngrep nmap nmon openssl procps snmp sysstat tcpdump tcptrace tcptraceroute telnet traceroute tshark vim wget gnupg python3 python3 pip for a
