• Debian base image
• perf installed for performance profiling
• Nginx included as a web server (modifiable)
• Privileged mode support for perf commands

start the container in a privileged mode, run:

docker run --name perf-utils --privileged -p 8080:80 -d ghcr.io/triplemcoder14/perf-utils:latest

create a bash shell in the running container, execute:

Once inside the container, you can run perf commands to probe your applications. Here are some examples:
