#go #k8s #devops

​​Gitpod is an open-source #k8s application providing fully-baked, collaborative development environments in your browser - powered by VS Code.

Tightly integrated with GitLab, GitHub, and Bitbucket, Gitpod automatically and continuously prebuilds dev environments for all your branches. As a result, team members can instantly start coding with fresh, ephemeral and fully-compiled dev environments - no matter if you are building a new feature, want to fix a bug or do a code review.

Features:
- Dev environment as code
- Prebuilt dev environments - automatically prepare environments on every Git push
- Professional developer experience in a browser tab (VS Code Extensions, full Linux terminals)
- Integrated Docker build
- GitLab, GitHub, and Bitbucket integration
- Integrated code reviews
- Snapshots - Snapshot any state of your dev environment and let others create clones
- Collaboration - Invite team members to your environments
- Gitpod CLI to automate your experience

​​Litmus helps Kubernetes SREs and developers practice chaos engineering in a Kubernetes native way.

Litmus is a toolset to do cloud-native chaos engineering. Litmus provides tools to orchestrate chaos on #k8s to help SREs find weaknesses in their deployments. SREs use Litmus to run chaos experiments initially in the staging environment and eventually in production to find bugs, vulnerabilities. Fixing the weaknesses leads to increased resilience of the system.

Litmus takes a cloud-native approach to create, manage and monitor chaos. Chaos is orchestrated using the following Kubernetes Custom Resource Definitions (CRDs):
- ChaosEngine: A resource to link a Kubernetes application or Kubernetes node to a ChaosExperiment. ChaosEngine is watched by Litmus' Chaos-Operator which then invokes Chaos-Experiments
- ChaosExperiment: A resource to group the configuration parameters of a chaos experiment. ChaosExperiment CRs are created by the operator when experiments are invoked by ChaosEngine.
- ChaosResult: A resource to hold the results of a chaos-experiment. The Chaos-exporter reads the results and exports the metrics into a configured Prometheus server.

Chaos experiments are hosted on hub.litmuschaos.io. It is a central hub where the application developers or vendors share their chaos experiments so that their users can use them to increase the resilience of the applications in production.

​​A temporary email right from your terminal.

tmpmail tmpmail is a command line utility that allows you to create a temporary email address and receive emails to the temporary email address. It uses 1secmail's API to receive the emails.

By default w3m is used to render the HTML emails on the terminal. But if you prefer another text based web browser or would rather view the email in a GUI web browser such as Firefox, simply use the --browser argument followed by the command needed to launch the web browser of your choice.

​​SQL powered operating system instrumentation, monitoring, and analytics.

osquery exposes an operating system as a high-performance relational database. This allows you to write SQL-based queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.

SQL tables are implemented via a simple plugin and extensions API. A variety of tables already exist and more are being written: https://osquery.io/schema. To best understand the expressiveness that is afforded to you by osquery, consider the following SQL queries:

 DISTINCT processes.name, listening_ports.port, processes.pid
  FROM listening_ports JOIN processes USING (pid)
  WHERE listening_ports.address = '0.0.0.0';

Automatic HTTPS for any #go program: fully-managed TLS certificate issuance and renewal.

Easy and Powerful TLS Automation. The same library used by the Caddy Web Server.

Caddy's automagic TLS features—now for your own Go programs—in one powerful and easy-to-use library! CertMagic is the most mature, robust, and capable ACME client integration for Go... and perhaps ever.

With CertMagic, you can add one line to your Go application to serve securely over TLS, without ever having to touch certificates.

certmagic.HTTPS([]string{"example.com"}, mux)

That line of code will serve your HTTP router mux over HTTPS, complete with HTTP->HTTPS redirects. It obtains and renews the TLS certificates. It staples OCSP responses for greater privacy and security. As long as your domain name points to your server, CertMagic will keep its connections secure.

Compared to other ACME client libraries for Go, only CertMagic supports the full suite of ACME features, and no other library matches CertMagic's maturity and reliability.
