Ubuntu 16.04 vmware image
I am using macOS, so will be using the brew package manager to install and manage my tools, if you are using Linux or Windows, use the appropriate install guide for each tool, according to your OS.įor each tool I will list the brew install command and the link to the install instructions for other OSes. This post is a guide through making those changes. It turns out that with Ubuntu 18.04 LTS (in particular the cloud image OVA) there are a few things need changed from the base install (namely cloud-init) in order to make them play nice with OS Guest Customisation in vCenter. I wanted a CLI only way to build a VM template for the OS and then deploy that to the cluster.

The following additional packages will be installed: With a Dockerfile, the Docker daemon can automatically build the container image.Įxample: The following is a basic Dockerfile which sets up an SSHd service in a container that we can use to connect to, and inspect other containers volumes, or get quick access to a test apt-get install -y docker-ce Dockerfiles: Dockerfiles are merely text documents (.yaml files) that contains all the configuration information and commands needed to assemble a container image.Then, using a single command, you can create and start all the services from that file. With Compose, a single configuration file is used to set up all of your application's services.
Docker Compose: Docker Compose is a tool that defines, manages and controls multi-container Docker applications.Any Docker container can run on any server that has the Docker-daemon enabled, regardless of the underlying operating system. Docker Engine: The Docker Engine is a layer that exists between containers and the Linux kernel and runs the containers.
