Hot reloading in Go applications
Modd is a library that makes hot reloading possible in Go applications. To use it, install it on your machine using the command below:
- Implement auto-reload after update
-
Ask HN: Can I see your scripts?
There's also modd[0] which allows for many file watch pattern -> command combos to easily be defined & run simultaneously from a modd.conf file.

Hot reload in golang
i was using cortesi/modd for this while using docker. Since I change to Rancher with dockerd i wasn’t able to get live reloading working again, i also tried air but no luck.. out of curiosity did anyone have a similar issue?

Live Reload in Go with Air
Interesting. I've been using https://github.com/cortesi/modd for this for a while but I'll check this project out.
- Ask HN: What developer tools would you like to see?
- Live previewing LaTeX document?
- docker-compose without dockers

Live Reloading in Golang using Air
me likes: https://github.com/cortesi/modd A little more flexible for various files

We don’t use a staging environment
I use a somewhat similar approach for Pirsch [0]. It's build so that I can run it locally, basically as a fully fledged staging environment. Databases run in Docker, everything else is started using modd [1]. This has proven to be a good setup for quick iterations and testing. I can quickly run all tests on my laptop (Go and TypeScript) and even import data from production to see if the statistics are correct for real data. Of course, there are some things that need to be mocked, like automated backups, but so fare it turns out to work really well.
You can find more on our blog [2] if you would like to know more.

A better, faster approach to downloading docker images without docker-pull: Skopeo
I decided to go searching for an alternative means to pull a docker image. In my search I discovered Skopeo, an alternative method to download Docker images that proved to be surprisingly effective. It not only downloaded the image faster, it also allowed me to save my image in a tar file, which means you can pull an image on one system and share that image to another system, loading it easily to docker instance on that system. This can be very beneficial if you have multiple systems and don't want to download an image multiple times.

[OC] Update: dockcheck - Checking updates for docker images without pulling - automatically update containers by choice.
But I'd suggest looking into if it's solved by other tools already, like regclient/regclient and their regsync features or something like containers/skopeo.

Wrapping Go CLI tools in another CLI?
Have a use case where we have a CLI (built with cobra) for our dev teams which can execute common tasks. One of those tasks we want to implement is to copy docker images from the internet to our internal registry. A tool such as skopeo can do this and much more. Instead of essentially re-writing the functionality directly into our CLI we'd like to embed it. This would also negate the need for the dev teams to manage multiple CLI tools.

Rails on Docker · Fly
Self hoisting here, I put this together to make it easier to generate single (extra) layer docker images without needing a docker agent, capabilities, chroot, etc: https://github.com/andrewbaxter/dinker
Caveat: it doesn't work on Fly.io. They seem to be having some issue with OCI manifests: https://github.com/containers/skopeo/issues/1881 . They're also having issues with new docker versions pushing from CI: https://community.fly.io/t/deploying-to-fly-via-github-actio... ... the timing of this post seems weird.
FWIW the article says
> create a Docker image, also known as an OCI image
I don't think this is quite right. From my investigation, Docker and OCI images are basically content addressed trees, starting with a root manifest that points to other files and their hashes (root -> images -> layers -> layer configs + files). The OCI manifests and configs are separate to Docker manifests and configs and basically Docker will support both side by side.

How are you building docker images for Apple M1?
skopeo is another tool worth looking into. we've started deploying amd and arm nodes into our k8s clusters, and this tool was incredibly easy to build around for getting multi-arch images into our container registry.

Get list of image architectures
I would use skopeo, the tool is quite handy for working with remote images. https://github.com/containers/skopeo

Implement DevSecOps to Secure your CI/CD pipeline
Using distroless images not only reduces the size of the container image it also reduces the surface attack. The need for container image signing is because even with the distroless images there is a chance of facing some security threats such as receiving a malicious image. We can use cosign or skopeo for container signing and verifying. You can read more about securing containers with Cosign and Distroless Images in this blog.

ImagePullPolicy: IfNotPresent - (image doesn’t exist in repo) - Is it possible to pull the micro service image from an EKS node and then push to repo?
Look at using tools like skopeo or crane

Monitoring image updates when not using :latest!
You could try some commandline tool like skopeo to fetch the image tags regularly and do some shell magic to notify you on any change you want

Containers without Docker (podman, buildah, and skopeo)
This is what Podman, an open-source daemonless and rootless container engine, was developed with in mind. Podman runs using the runC container runtime process, directly on the Linux kernel, and launches containers and pods as child processes. In addition, it was developed for the Docker developer, with most commands and syntax seamlessly mirroring Docker's. Buildah, an image builder, and Skopeo, the image utility tool, are both complimentary to Podman as well, and extend the range of operations able to be performed.
