Docker

Build Docker image from local Dockerfile with name and tag ubuntu:mine

docker build -t ubuntu:mine .

Run Docker image ubuntu:mine interactive /bin/bash, don't keep changes and mount local directory to /project From Linux etc.:

docker run --rm -it -v $(pwd -P |sed 's#/mnt##'):/home -v /c:/c ubuntu:mine /bin/bash

From Windows cmd: (replace with where you checked out this project) docker run --rm -it -v c:<windows path>:/home -v c:/:/c ubuntu:mine /bin/bash

Agenda

My plans for today

• Motivation (I really like unix cmd line...)
• Example: What code is used to build "this app"

eval "$(oc get dc mtw-m-settings -n mtw-atest -o json |jq -r '.spec.template.spec.containers[]|.image'|sed 's;.*5000/\(.*\)/\(.*\);oc get isimage -n \1 \2 -o json;')" | jq '.image.dockerImageMetadata.Config.Labels|to_entries[]|select(.key|startswith("io.openshift.build.commit"))'

• find
• grep
• sed
• curl
• jq
• for
• while
• xargs
• variable ops
