Using docker with Microsoft Azure

docker.md

Creating docker application from local system using Docker CLI

• To create a machine using Docker CLI:
  • docker-machine create --driver azure --azure-subscription-id <subs-id> --azure-location <location:eg. eastus> --azure-resource-group <resource-group-name if created/otherwise created automatically> --azure-size <vm-name> <machine-name>

NOTE: Every Resource group has upto 10 CPU Core limit, so if you get issues creating newer instances solution is to create a new resource group.

VM Sizes:

• Listed here: VM Sizes
• Naming convention is as provided: Standard_A1/Basic_A1, etc

Sometimes there are issues with Docker getting installed, it seems Azure guys get the bleeding edge version. Refer to the issue: Xenial (16.04) - Failed to start Docker Application Container Engine #22371

Solution is:

• Remove Docker:

  • sudo apt-get remove docker*
  • sudo apt-get autoremove
  • sudo apt-get autoclean

• Install previous version of docker (17.04.0ce worked for me)

  • curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
  • sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
  • sudo apt-get update
  • sudo apt-get upgrade
  • apt-cache policy docker-ce
  • sudo apt-get install -y docker-ce=<version-name>

• Edit /etc/default/docker file and add the option:

  • DOCKER_OPTS="-s overlay"

• Then

  • systemctl restart docker.service

Adding user to sudo,docker group:

• sudo usermod -aG docker ${USER}
• su - ${USER}
• id -nG
• sudo usermod -aG docker username
