2. The pain
❖ Between brownfield/heavy and green
field…there are plenty of lightweight
to medium weight applications
❖ Is it possible to migrate to containers
without re-factoring and re-
architecting them? For some, YES!
❖ I don´t trust base images
3. Some band-aids
❖ Different approaches are possible…
❖ Image of your own
❖ Import from VM
❖ Use Config Mngt tools {Puppet, Chef, Salt, Ansible…
❖ Packer.io
4. Doing the hard way
❖ apt-get install —yes debootstrap
❖ sudo debootstrap --variant=minbase trusty trusty
❖ sudo chroot trusty/ bash
❖ rm -rf /boot
❖ exit
❖ tar -C trusty/ -c . | docker import - mytrustedimage
❖ docker run -d -it mytrustedimage bash
