Project

Small docker project

Tagged admin , bash , dev

I really like docker (even if I will look at [systemd-nspawn](http://www.freedesktop.org/software/systemd/man/ systemd-nspawn.html)), and also gulp. So I decided to create a small tool for serving a directory with a livereload.

The repo is available here

What I have learned

  • Docker, especially with boot2docker (I am on MacOSX shame on me), is not really flexible:

    • no evaluation for environment variables

    • you can not store a variable through multiple run, you will need to do a oneliner e.g:

      # you will need to write this in the Dockerfile
RUN TMPFILE=$(tempfile) && \
  echo "Hello World" > $TMPFILE && \
  rm $TMPFILE

    • you cannot build remotely from a custom branch: [see this post](http://stackoverflow.com/questions/25509828/ can-a-docker-build-use-the-url-of-a-git-branch)

    • accessibility to the container through boot2docker is pretty hard: [see this post](http://stackoverflow.com/questions/28047809/ docker0-interface-missing-on-osx/)

  • awk is an awesome tool for manipulating strings and console outputs. Best one hour investment so far. If you have to write bash scripts, awk is definitely a best to know tool.

  • nodejs is definitely a hell for developers but is the only platform for frontend dev. Here are some issues I have gone through:

    • bug in collecting interfaces which forced me to use a syscall: bug report
    • npm ecosystem is messy. You will have to test many plugin, which does quite the same thing, to find the one with THE option you need. And finally find that the lib is 10 lines long and wraps another lib.
    • no good packaging, which leads to a custom installation path, thanks [this blog post](https://nodesource.com/blog/ nodejs-v012-iojs-and-the-nodesource-linux-repositories) for the help.

  • gulpjs is way better than grunt and must be ported to other languages, really excited about the 4.0 version coming soon.

How I can improve

The tool is currently working, I am thinking of adding a markdown compiler in the chain because I really use markdown all the time.

I still have to test it a bit to be sure it is okay to make a release (first thing I release yay \o/)
