In a previous article, I described how to expose a Github source repo as a public Helm repository by enabling Github Pages and running the chart-releaser utility. In this article, I want to remove the manual invocation of the chart-releaser, and instead place that into an Github Actions workflow that automatically publishes changes to the … Helm: automated publishing of Helm repo with Github Actions
The only requirement for a public Helm chart repository is that it exposes a URL named “index.yaml”. So by adding a file named “index.yaml” to source control and enabling Github Pages to serve the file over HTTPS, you have the minimal basis for a public Helm chart repository. The backing Chart content (.tgz) can also … Helm: manually publishing Helm repo on Github using chart-releaser
My previous article on multi-stage builds to create Docker images for Go laid the foundation for using an intermediate image as the builder your Go binary. However, this example was intentionally simplistic and did not address package and dependency management. Since the release of Go 1.11, the standard tooling has natively supported the concept of … GoLang: Go modules for package management during a multi-stage Docker build
If you are on an Ubuntu host and need to determine from which package a file originated, the ‘dpkg’ utility has this ability. For example, if you need to know which package the ‘mkpasswd’ binary came from: $ which mkpasswd /usr/bin/mkpasswd $ dpkg -S /usr/bin/mkpasswd whois: /usr/bin/mkpasswd Which tell us it came from the ‘whois’ … Ubuntu: Determining the package origin of a file
It is common in secure production datacenters for internal hosts to be forced to go through a reverse proxy for public internet access. The same concept can be applied to apt package management, where setting up a centralized package proxy enables caching as well as security controls. In a datacenter where you could have hundreds … Ubuntu: A centralized apt package cache using Apt-Cacher-NG
It is common in secure production datacenters for internal hosts to be forced to go through a reverse proxy (e.g. Squid) for public internet access. The same concept can be applied to apt package management, where setting up a centralized package proxy enables caching as well as security controls. In a datacenter where you could … Ubuntu: A centralized apt package cache using squid-deb-proxy
If your Salt Minion version is too far removed from the Salt Master version, you may find yourself with unexplained errors. This problem can be faced when the OS template you are deploying was packaged years earlier with an older Salt minion while the Salt Master has been kept up to date. But it can … SaltStack: Installing an older Salt Master or Minion for compatibility
Downloading 3rd party packages from github is made very simple in the Go language with the import statement. But similar to other languages, the complexity of versions and inter-dependencies begs the use of a package manager for any projects that are non-trivial (think npm for Javascript, pip for Python, Maven for Java, etc.). Glide is a package manager for the Go … GoLang: Glide for Go language package management
Using 3rd party packages from github is made very simple in the Go language with the import statement. But one problem is that “go get” will always pull the HEAD of the master branch and there is no way to explicitly specify another branch. The ultimate answer would be to use a package dependency manager like Glide, which … GoLang: Vendor directory for github branches other than master
If you have worked on deploying packages via apt-get, you are probably familiar with a couple of forms of interruption during the package installation and upgrade process. The first is the text menu shown during package upgrades that informs you that a new configuration file is available and asks if you want to keep your … Ubuntu: Silent package installation and debconf
In a production environment, it is common to have restricted internet access on the production deployment hosts. This means that using the standard ‘npm install’ and pulling modules from the registry.npmjs.org repository is not an option. Given the breadth of the dependency graph required for most modules, this packaging is something you want automated without … Node.js: Packaging modules for offline deployment using npm-bundle
