I installed telnet in an IRIS container using:

docker exec -u root -it <container-name> apt-get install telnet

Then tested it using:

docker exec -u root -it <container-name> telnet <target-ip> <target-port>

This requires your container to be networked with the target. So a full example:

    docker network create networkECP
    docker network connect networkECP iris-data-server
    docker network connect networkECP iris-app-1
    docker network inspect networkECP
    docker exec -u root -it iris-app-1 ping iris-data-server
    docker exec -u root -it iris-app-1 apt-get update && apt-get install telnet
    docker exec -u root -it iris-app-1 telnet iris-data-server 1972
