buildah VS micro-editor

For the task of building the graph image, my first idea was to rely on buildah. In fact, our design was already heavily relying on containers/image for all things regarding copying images from one registry to the other, or from one registry to an archive. The obvious choice was to use the same suite of modules in order to keep dependencies to a minimum.

I appreciate that podman can run daemonless, but I've gotten tired of waiting for them to implement heredoc support and have continued to use docker.

You do realize that, under the hood, buildah uses a container engine (runc by default)? See https://github.com/containers/buildah/blob/main/docs/buildah...

buildah

I found this small tutorial: https://github.com/containers/buildah/blob/main/docs/tutorials/04-include-in-your-build-tool.md and it works.

Last week, Buildah version 1.29 was also released. The prune command has been added to clean intermediate images as well as the build and mount cache.  Support for the –group-add option to the from and build commands was added. One useful feature of this, it to use the –group-add keep-groups option, which allows rootless users to take advantage of their group access to file and devices mounted into the build containers. And the –cache-from and –cache-to options for the build command now allow for multiple sources. This can be used to improve the speed of builds, especially in CI/CD environments.

Unfortunately this syntax is not generally supported yet - it's only supported with the buildkit backend and only landed in the 1.3 "labs" release. It was moved to stable in early 2022 (see https://github.com/moby/buildkit/issues/2574), so that seems to be better, but I think may still require a syntax directive to enable.

Many other dockerfile build tools still don't support it, e.g. buildah (see https://github.com/containers/buildah/issues/3474)

Useful now if you have control over the environment your images are being built in, but I'm excited to the future where it's commonplace!

Not sure these are really popular, but I cannot resist advertising a few utilities written in Go that I regularly use in my daily workflow:

- gdu: a NCDU clone, much faster on SSD mounts [1]

- duf: a `df` clone with a nicer interface [2]

- massren: a `vidir` clone (simpler to use but with fewer options) [3]

- gotop: a `top` clone [4]

- micro: a nice TUI editor [5]

Building this kind of tools in Go makes sense, as the executables are statically compiled and are thus easy to install on remote servers.

> The worst way to store and manipulate text is to use an array.

Claim made from theoretical considerations, without any actual reference to real-world editors. The popular Micro[1] text editor uses a simple line array[2], and performs fantastically well on real-world editing tasks.

Meanwhile, ropes are so complicated that even high-quality implementations have extremely subtle bugs[3] that can lead to state or content corruption.

Which data structure is "best" is not just a function of its asymptotic performance. Practical considerations are equally important (arguably more so).

There are two main ways to configure sudo.The first one is using the sudoers file.It is located at /etc/sudoers for Linux,and /usr/local/etc/sudoers for FreeBSD respectively.The paths are different,but the configuration works in the same way. A typical sudoers file looks like this. The sudoers file must be edited with the visudo command,which ensures the config is free of errors.Running this command as the root user will result in opening vi by default.If you want to use a different editor you can set the VISUAL environment varaible to the editor you want. For example,if you want to use micro as the text editor run:

found that micro has dedicated info page for copy paste

micro: winget install zyedidia.micro
