vagrant ssh (issue)
Ik kon geen "vagrant ssh" uitvoeren omdat ssh niet op het pad stond. Wel kon ik (via Windows menu) Git Bash openen, "cd /c/Data", dan "$ cd cgi-docker-workshop/vagrant/" dan "vagrant ssh" uitvoeren.
images and containers
With docker ps the runnning containers are listed, and docker images lists the images. So when I want to cleanup the images, the docker rmi command helps. Unfortunately there can still be a container using this image and the rmi fails. So where are the containers?
When using docker ps -a it lists all containers that you have and probably already forgot. (Enable the QuickEdit mode in your command shell). Then docker rm container_name removes one. I noticed that there can be many names or container id's in one rm, so it is easy, using QuickEdit, to copy paste the container names to be removed.
Note: the docker images -a also lists more images.
Please add the removal and cleanup to your lab.
Lab 2 verwissel -y met argument ervoor
De -y staat op de verkeerde positie, schuif deze 1 argument naar voren.
Lab 2, laatste stap
Bij in de laatste stap run je geen nodejs maar de hellonode. Als je nodejs start, dan blijkt deze gelijk al weer te stoppen (docker ps geeft geen lijst).
Dus:
docker run -d -p 8080:8080 username/hellonode
Lab 2 na run, open browser?
Na de laatste docker-run verwacht ik in een opdracht de http://localhost:8080 te moeten openen. En eventueel om vooraf met netstat te controleren of een poort al in gebruik is.
