Installing .NET 8 Runtime on Ubuntu 22.04 Docker Image

 .NET 8 was release on November 14. There are docker container images for .NET 8 available for dotnet runtime and can be found with tag list here https://mcr.microsoft.com/v2/dotnet/runtime/tags/list . However, if you want to setup .NET 8 runtime on another specific Linux docker image for example on ubuntu:jammy , amd64/ubuntu:22.04 or with a special image such as ffmpeg Linux server image linuxserver/ffmpeg:amd64-version-6.0-cli, where you might want to run your .NET app to use ffmpeg, In such cases, where you you might have to setup .NET 8 runtime on a specific docker image, with your other tools readily available, details mentioned may come in handy.   Lets, see how we can install .NET 8 runtime on base Ubuntu 22.04 images, using a docker file.

Deploying Azure Resource Group with Ansible Play Book Using Custom Ubuntu 18.04 VM

In a previous post we have discussed how to setup Ansible on Azure Ubuntu 18.04 VM. We can start using Ansible and execute play books to deploy Infrastructure on Azure cloud. Let’s look at how we can get started with deploying resources to Azure using an Ansible playbook, on the VM we created with Ansible as explained in the post “Install Ansible to Use Python3 on Azure Ubuntu 18.04 VM”.

Open SSH Connection in VS Code to Azure Ubuntu VM to Perform Remote Development

VS Code is a useful development tool which can be used on any platform to develop code in any language of your preference. In an Azure Ubuntu VM without setting up the desktop remote access, you may want to perform development work and may want to perform debugging activities, as you are doing with local files in a Linux environment. You can use ssh extension for VS Code and create ssh connection to a VM in Azure or anywhere over ssh and work connected to the remote Linux, MacOS or Windows machines via VS Code. Let’s look at steps to connect to a Ubuntu VM on Azure using a VS Code in Windows 10 local machine.

Install Ansible to Use Python3 on Azure Ubuntu 18.04 VM

Ansible is an open-source configuration and infrastructure management tool providing capability to implement infrastructure as code (IaC). Especially in Linux based implementations ansible is used heavily, however, it can support automation on Windows platform as well. Let’s learn some Linux IaC with ansible in the coming posts and in this post, lets try to setup an ansible installation on a Ubuntu 18.04 VM with python3 support, in Azure. Setting up user for ansible in the VM was explained in previous post “Create New Linux Admin User in Azure Ubuntu VM”.

Create New Linux Admin User in Azure Ubuntu VM

We can setup Linux VMs in Azure for various reasons. Maybe it is for setting up a Jenkins or Ansible server. If we are setting up Ansible on a Linux VM in Azure it is recommended to use a separate user with Admin permissions, instead of the default user who has the root access as well. This is beneficial as in case we need to reset access for the default user, we can do so without harming anything setup for Ansible. In this post let us look at steps to add an additional admin user to Ubuntu Linux VM in Azure and how we can enable ssh to the VM with that user.
