This is a container which can be used for various debug tasks in Docker and Kubernetes. It is designed to contain many useful tools or you can extend it if needed.

You can run it as a container in Docker or as a pod in Kubernetes then exec into it and use tools like netcat or mysql client "inside". It is also listenting on port 8080 portocol http so you can check that.

docker buildx build --platform linux/amd64 --push -t vvang/dummy:amd64  . 

export TAG=0.3
docker build -t dummy:$TAG .

docker run -d  -p 6789:8080 --name dummy dummy:$TAG
curl http:https://localhost:6789/cgi-bin/status

The default port inside container is 8080 and the default message is "ok". Those can be changed with environment variables PORT and TEXT, for example:

docker rm -f dummy
docker run -d  -e TEXT=nobine -e PORT=8181 -p 6789:8181 --name dummy dummy:$TAG
curl http:https://localhost:6789/

The container includes some small scripts which can be accessed with URLs like http:https://localhost:6789/cgi-bin/status. For others see the directory cgi-bin here.

You will need to push it to an image repository. If you wish to use my container from docker hub, try the name vvang/dummy:0.3 or whatever tag is listed at https://hub.docker.com/r/vvang/dummy

You can just create the pod with an imperative command:

kubectl run dummy --image=vvang/dummy:0.3  # optional -n namespace

Or you can use the provided yaml file which also shows the use of environment variables and other goodies.

To enter inside a pod, use:

kubectl exec -ti dummy -- bash
    root@dummy# ps -ef
    root@dummy# ifconfig
    root@dummy# exit

We recommend to leave this pod there but if you want to delete it:

kubectl delete pod dummy  # optional -n namespace
