Gpg Key Generate Docker Vs Vm

Oct 12, 2018  Since we want to create a new VM click add. Now we are in the Virtual Machine wizard with a lot of options. Note that most options depend on your case. First we will acquire the Docker GPG key, we verify using a fingerprint and download the Ubuntu repository. We update apt-get once more and install Docker-ce. Recently a new Docker release 17.03.1.ce was announced for Oracle Linux 7. In the example below, I'm using Oracle Linux yum server to provide the software updates. With a few quick steps, you'll be able to install the latest Docker release.

Almost ready

Also, while it's not required at all, you might still want to have the Azure CLI to check the names of the VM images you wish to use, as well as the VM sizes available:

Ready?

You can check out all of the options available by running:

For now, I'll put here the command I use to create them. Notice that since I prefer using Debian Jessie instead of Ubuntu Server for my Docker Hosts, I'll set that option in this example:

Key
  • azure-image: The base image used for the VM - Get a list using Azure CLI: azure vm image list --location southcentralus --publisher credativ
  • azure-size: The size of your VM - Get a list using Azure CLI: azure vm sizes --location southcentralus
  • azure-subscription-id: The ID of the subscription you want to use to create the VM. You can check out your available subscription ID's using Azure CLI: azure account list

Docker commands in the host

Before attempting to issue docker commands inside the host (i.e. entering via SSH using docker-machine ssh my-docker-host), you'll need to add the ssh user of the machine you just created to the docker group.

If you followed the instructions (using the Debian Jessie VM Image), then you'll need to issue the following command right after you've created the host:

Dude, where's my configuration???

If you followed this guide correctly, the configuration is not at /etc/defaults/docker..

..it's at /etc/systemd/system/docker.service, because it's using systemd (see custom-docker-daemon-options for Systemd)

Gpg Generate Key

What about swarm options on docker-machine?

Gpg Key Generate Docker Vs Vms

Right now (version 0.8.1), they won't use the native swarm available on docker >= 1.12, so I don't use it at all. 256 bit encryption key generator.
