Dynamic watermarking with imgproxy and Apache APISIX

Last week, I described how to add a dynamic watermark to your images on the JVM. I didn't find any library, so I had to develop the feature, or, more precisely, an embryo of a feature, by myself. Depending on your tech stack, you must search for an existing library or roll up your sleeves. For example, Rust offers such an out-of-the-box library. Worse, this approach might be impossible to implement if you don't have access to the source image.

Another alternative is to use ready-made components, namely imgproxy and Apache APISIX. I already combined them to resize images on-the-fly.

Random and fixed routes with Apache APISIX

My ideas for blog posts inevitably start to dry up after over two years at Apache APISIX. Hence, I did some triage on the APISIX repo. I stumbled upon this one question:

Even more OpenTelemetry!

I continue to work on my Opentelemetry demo. Its main idea is to showcase traces across various technology stacks, including asynchronous communication via an MQTT queue. This week, I added a couple of components and changed the architecture. Here are some noteworthy learnings; note that some of them might not be entirely connected to OpenTelemetry.

HTTP Request Smuggling in forward-auth Plugin (CVE-2024-32638)

For APISIX versions 3.8.0 and 3.9.0, enabling the forward-auth plugin allows APISIX to trigger illegal requests (HTTP Request Smuggling).

Five ways to pass parameters to Apache APISIX

I recently read 6 Ways To Pass Parameters to Spring REST API. Though the title is a bit misleading, as it's unrelated to REST, it does an excellent job listing all ways to send parameters to a Spring application. I want to do the same for Apache APISIX; it's beneficial when you write a custom plugin.

Monthly Report (April 01 - April 30)

We have recently made some additions and improvements to specific features within Apache APISIX. These include adding discovery k8s dump data interface, adding max req/resp body size attributes (max_resp_body_bytes and max_req_body_bytes) in the kafka-logger plugin, and autogenerating the admin API key if they are not configured in the configuration file. For detailed information, please read the monthly report.

Release Apache APISIX 3.8.1

We are glad to release Apache APISIX 3.8.1 with a bug fix to improve user experiences.
