The nginx Config Generator tool helps me inspect the input and output without writing a one-off script first.https://ilham.dev/posts/how-to-build-find-command-safely/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-build-find-command-safely/The find command is one of the most useful Linux commands, but it is also one of the commands I treat with respect. It can search thousands of files very quickly, and with the wrong option it can also delete thousands of files very quickly.https://ilham.dev/posts/how-to-build-nginx-reverse-proxy-config/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-build-nginx-reverse-proxy-config/An nginx reverse proxy config can look intimidating when you are still learning: server { listen 80; server_name app.example.com; location / { proxy_pass http://127.0.0.1:3000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } The config is not random.https://ilham.dev/posts/how-to-check-common-port-numbers/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-check-common-port-numbers/Port numbers are labels for network services, but a port number alone does not guarantee what is actually running there. The Port Reference tool helps me inspect the input and output without writing a one-off script first.https://ilham.dev/posts/how-to-filter-docker-logs-without-losing-context/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-filter-docker-logs-without-losing-context/Docker logs can get noisy very quickly. A service may print hundreds or thousands of lines, and the line you need is often buried in the middle. The basic command is:https://ilham.dev/posts/how-to-parse-logs-before-searching-randomly/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-parse-logs-before-searching-randomly/Logs become easier to investigate when they are split into fields instead of treated as one giant wall of text. The Log Parser tool gives me a safe place to test the idea before I put it into a script, server, or production workflow.https://ilham.dev/posts/how-to-read-yaml-without-getting-lost-in-indentation/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-read-yaml-without-getting-lost-in-indentation/YAML is readable when indentation is correct and confusing when it is not. A viewer helps validate and inspect the structure. The YAML Viewer tool is useful because it lets me check the result in a small, controlled place before I use it in a bigger workflow.https://ilham.dev/posts/how-to-sort-env-files-without-moving-comments-to-the-wrong-place/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-sort-env-files-without-moving-comments-to-the-wrong-place/A messy .env file makes configuration harder to review. Sorting helps, but comments and duplicates need care. The .env Key Sorter tool gives me a safe place to test the idea before I put it into a script, server, or production workflow.https://ilham.dev/posts/how-to-use-ssh-tunnel-builder/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-use-ssh-tunnel-builder/SSH tunnels are powerful, but the flags are not friendly at first sight: ssh -L 8080:localhost:80 user@example.com The command is short, but the meaning is not obvious. Which machine is localhost?https://ilham.dev/posts/how-to-turn-docker-run-into-compose/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-turn-docker-run-into-compose/A docker run command is fine when it is short. But after a few ports, volumes, and environment variables, it becomes hard to read and easy to break. You may see something like this:https://ilham.dev/posts/how-to-write-a-dockerfile-without-copying-random-examples/Sun, 27 Sep 2026 00:00:00 +0700https://ilham.dev/posts/how-to-write-a-dockerfile-without-copying-random-examples/A Dockerfile is a recipe for building an image. The clearer the recipe, the easier the container is to rebuild and debug. The Dockerfile Builder tool gives me a safe place to test the idea before I put it into a script, server, or production workflow.
