Docker Nspawn

Don’t want to use Docker? Still want to start containers for tests or whatever? Don’t want to install yet another software to perform this? Want to understand a bit of how all those things work? Great! I will show you how to boot a container from the internet only through systemd-nspawn Thanks to the CoreOS team (love those guys) a new hub for storing container now exists: quay. The other good news is the ACI, the container image format defined in the App Container (appc) spec. Read More...

Curl utils

Here are some options and command I use with curl when dealing with stuff I have to develop. curl -si <ip> # -s is the silent flag, it removes the progress # -i displays the headers curl -X POST -H "Content-Type: application/json" -u "admin:admin" -d '{}' <ip> # -X set up the http method (here POST) # -H set up an header, format is: "header_name: value" # -u support for Basic Auth, format is: "user:password" # -d set up data to send to the server I mostly use those options, the -s is really interesting when you want to grep the content.

Gogs + Drone

Jenkins is everywhere now, but I really don’t like it. So I am looking at a replacement from day to day. I discovered Gogs an I though that a CI is also a good use case for the Golang language. And I finally found Drone (which was not really difficult as it is mentionned in a ticket on gogs github). So I decided to make them work together in order to test that. Read More...

Pytest command line

I have recently dug into pytest documentation, and moreover into the command line arguments and I finally found a better workflow for running tests while I develop. Here is the command I run when I just made some devs: py.test -xvvvs --tb=line --pdb -x will stop execution on first failue, useful when debugging tests in order of appearance (recommended) -vvv will display current test path (reuasable in py.test), the path will avoid to rerun all the previous tests before going to the one you are currently working on.

Test promises with jasmine

Jasmine is a good testing framework, which I really like, it is really powerfull and has just the amount of features to perform a huge variety of tests. At some point I had to tests promises, and more generally testing that some part of a function is not called (you will have to adapt the snippet but the idea is here). It is pretty simple, but not well known (I checked some stackoverflow threads before finding this). Read More...

HTML5 Boilerplate

Sometimes we only need to have a boilerplate quickly to test it through a browser. We only want to have the basis, and having it working fine. You can find here a good generator for what you want. But sometimes, having a snippet in the bash prompt can be needed. So here is an example: # stop script if something bad happen set -e # unzip need to have a tempfile to extract properly TMPFILE="/tmp/tempfile. Read More...
