argocd-image-updater VS Fluentd

Use the ArgoCD image updater

We already have software agents in GitOps ecosystem that modify the state in git. Ie, the image updater in ArgoCD. It watches the docker registry. When it sees a new image, it updates git on a user's behalf.

If you are using ArgoCD you might be able to use this: https://argocd-image-updater.readthedocs.io/en/stable/

I just found this in my travels, I have only gone so far as reading the introduction but seems to be a fit? https://github.com/argoproj-labs/argocd-image-updater

I've used Keel and more recently ArgoCD Image Updater (Using ArgoCD to manage deployments).

Use the image updater

To answer your question you should promote docker images between environments. There are many ways to do this. Check https://argocd-image-updater.readthedocs.io/en/stable/ if you haven't seen it already.

For ArgoCD there’s argocd-image-updated, https://argocd-image-updater.readthedocs.io/en/stable/

Get Started with Fluentd

Currently, there is no cluster-wide logging. Fluentd can be used to have a unified logging layer for the cluster.

Fluentd hasn't been touched for 8 years? Looking at the repo it looks like it's alive and well. https://github.com/fluent/fluentd

Fluentd is an open-source log management and data collection tool. Just like Logstash, Fluentd uses a pipeline-based architecture. This allows it to collect data from various sources and network traffic and forward it to various destinations.

Fluentd is a powerful log management tool that offers organizations the flexibility and scalability required to handle large volumes of log data from a variety of sources and transport it to various destinations. Utilizing a flexible and modular architecture, Fluentd allows users to easily add new input and output plugins to integrate with a wide range of systems and applications. It supports a wide range of data sources and destinations, including databases, message queues, and data stores.

Substation is an affordable alternative to products like Cribl (~10x cost savings) and is easier to manage than similar open-source projects such as Logstash and fluentd. It's been used in production by the security team at Brex for 2+ years and is ready for any scale, even beyond 100,000 events per second!

There are probably too many to chose from. Logstash, Promtail, Vector, Filebeat, FluentD, Logagent and probably many more

To alleviate some of the pain, it’s a good idea to use industry standards and tooling like OpenTelemetry (https://opentelemetry.io). For data collection specific to logs, open-source tools like LogStash and Fluentd are also popular.

Created and maintained by the creators of fluentd, fluentbit is a lightweight, fast, and scalable logging and metrics processor and forwarder. Built specifically for the cloud and containerized environments, it allows users to collect data from any source, enrich it with filters and forward it to the tool of their choice.
