Install Docker on Google Cloud Platform with Ubuntu Vivid 15.04
Ubuntu 15.04 (Vivid Vervet) has switched the init manager from Upstart to systemd. Will the Docker installation change? Let’s give a try and install it on a Google Compute Engine instance.
Install Docker:
1
$ curl -sSL https://get.docker.com/ | sh
Add user to Docker group for running commands without sudo:
1
$ sudo usermod -aG docker ${USER}
Log out, then log back in.
Verify the installation:

$ docker run hello-world
Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker Hub account:
