docker tips and tricks

README.md

fix slow networking

see hashicorp/vagrant#1807

boot2docker down
VBoxManage modifyvm "boot2docker-vm" --natdnsproxy1 on
VBoxManage modifyvm "boot2docker-vm" --natdnshostresolver1 on
boot2docker up

fix broken daemon connection when using VPN

see boot2docker/boot2docker#628

boot2docker down
vboxmanage modifyvm "boot2docker-vm" --natpf1 "docker,tcp,127.0.0.1,2376,,2376"
boot2docker up

then in your bash profile add:

$(boot2docker shellinit)
export DOCKER_HOST=tcp://127.0.0.1:2376

running docker-machine with fusion 5

see hashicorp/vagrant#3667

1. docker-machine -D create --driver vmwarefusion osxdock --vmwarefusion-memory-size 2048
2. this fails, but now you can go and edit the osxdock.vmx file.
3. change virtualHW.version = "9" to virtualHW.version = "9"
4. change guestOS = "other3xlinux-64" to guestOS = "otherlinux-64"
5. attach the boot2docker.iso, and start the VM
6. let it install everything.
7. change the root password so you can ssh and copy things, etc.
8. scp root@192.168.134.142:/var/lib/boot2docker/tls/* /Users/myusername/.docker/machine/machines/osxdock/ (change ip and username...)

alias vmrun="/Applications/VMware\ Fusion.app/Contents/Library/vmrun"
vmrun -gu docker -gp tcuser directoryExistsInGuest /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx /var/lib/boot2docker
vmrun -gu docker -gp tcuser CopyFileFromHostToGuest /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx /Users/$USER/.docker/machine/machines/osxdock/userdata.tar /home/docker/userdata.tar
vmrun -gu docker -gp tcuser runScriptInGuest /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx /bin/sh \
"sudo /bin/mv /home/docker/userdata.tar /var/lib/boot2docker/userdata.tar && \
sudo tar xf /var/lib/boot2docker/userdata.tar -C /home/docker/ > /var/log/userdata.log 2>&1 && \
sudo chown -R docker:staff /home/docker"
vmrun -gu docker -gp tcuser enableSharedFolders /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx
vmrun -gu docker -gp tcuser addSharedFolder /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx Users /Users
vmrun -gu docker -gp tcuser runScriptInGuest /Users/$USER/.docker/machine/machines/osxdock/osxdock.vmx /bin/sh \
"sudo mkdir /Users && \
sudo mount -t vmhgfs .host:/Users /Users"

1. if you did things right, docker-machine env osxdock should now work.
2. try out docker-machine restart osxdock to make sure you won't have issues later.

good to go!
