While setting up a GitLab CI build & deployment pipeline for one of our customer projects, I had the need to expose GitLab's environment-specific variables in multiple jobs as I needed the information in the build & deployment steps. Since I needed to run the jobs on different servers, I was not able to combine both jobs.

Deployer is a valuable tool that simplifies and automates the deployment process of PHP applications in a traditional non-container environment.

Following our guide to set up Traefik, Docker, and Compose with multiple networks, I ran into a problem:

a network with name customer_staging_default exists but was not created for project "customer_staging"
Set `external: true` to use an existing network

network customer_staging_default was found but has incorrect label com.docker.compose.network set to "staging_default"

One of my recent tasks was to run an upgrade of a production PostgreSQL database. Since we have PostgreSQL running in a Docker container in our Hashicorp Nomad environment, I assumed it would be enough to switch to a new Docker image and everything would be working fine.

For traditional non container deployments, Deployer is a value tool to simplify & automate the deployment process of a PHP application. Thanks to its collection of default deployment recipes, Deployer can be used out-of-the-box for deployments.

Since migrating to my Windows 10 & WSL2 setup a few years ago, I regularly try to reclaim disk space from my WSL2 setup by following the steps outlined in Scott Hanselman's blog post. However, this time it did not work as expected.

In our Techradar we've listed DDEV as a tool to assess. But why?

For a few of our customer projects, we use Tideways to spot performance bottlenecks and get real-time error detection alerts.

As a bonus, Tideways can track deployment events to compare performance and failure rates before and after the deployment.

In Traefik providers are infrastructure components (e.g. container engines, cloud providers, or key-value stores) that can be queried in order to find relevant information about the routing configuration.

Internally we develop our own tools, that we use as CLI. To make it easier to distribute and use them, we create standalone binaries. But often the files are huge.

So let's see how we can make them smaller without losing any functionality.
