Client Setup¶

Access the web-terminal¶

When running the lab for Kubernetes Extensions, you can make use of a web-terminal. The Dockerfile to use is located in https://github.com/IBMAppModernization/web-terminal, and named Dockerfile-s2i-oc-tekton-operator.

To run on localhost as a Docker container,

git clone https://github.com/IBMAppModernization/web-terminal.git
cd web-terminal
docker build --no-cache -t web-terminal:latest -f Dockerfile-s2i-oc-tekton-operator .
docker run -d --restart always --name terminal -p 7681:7681 -v $HOME/dev/tmp:/root/dev web-terminal
docker ps -a
CONTAINER ID    IMAGE    COMMAND    CREATED    STATUS    PORTS    NAMES
85edc0b0ec27    web-terminal    "ttyd -p 7681 bash"    17 minutes ago    Up 17 minutes    0.0.0.0:7681->7681/tcp   terminal

The volume mapping will write all files under the working directory to the host directory $HOME/dev/tmp. So suppose my host's user home directory is /Users/remkohdev@us.ibm.com/. If I open the terminal in the browser, the working directory for the user is /root. Any file that is created under /root is created on the host's directory $HOME/dev/tmp. Similarly if I create a file in $HOME/dev/tmp it is available in the container's /root directory.

Open the web-terminal in a browser and go to http://0.0.0.0:7681.
