Use it to control stuff but I wanted it to do more like release and deploy the stuff I build. This is how you can integrate Alexa voice service with Jenkins. First setup the server For receiving commands from Alexa and sending them to Jenkins we need a server and some code. First start with the server i use docker and a docker-compose to set it up. https://lifeandshell.com/posts/autodeploy-docker-images-aws-git-push-deploy/ Thu, 26 May 2016 12:56:19 +0000 https://lifeandshell.com/posts/autodeploy-docker-images-aws-git-push-deploy/ So I have a lot of small project and some large. To buil in quality into my code i need to run test in my code. And my code in a prod like env. I always uses docker so my dev env are verly like my prod. One key thing that i do is that when i push code to my master branch i do a release do server. This is so that i can verify that everything is working and i can run test on it. https://lifeandshell.com/posts/python3-and-rabbitmq/ Tue, 21 Apr 2015 22:38:05 +0000 https://lifeandshell.com/posts/python3-and-rabbitmq/ Im using rabbitmq in some of my python apps.

I followed the guide from this page http://lepture.com/en/2013/create-oauth-server And after some work I got an working server and client running on my Centos server. The code only uses an sqlite db and are only testing the OAuth functions so for a working solutions there are some more work. https://lifeandshell.com/posts/recover-you-python-files-from-rm-rf/ Thu, 03 Apr 2014 14:49:50 +0000 https://lifeandshell.com/posts/recover-you-python-files-from-rm-rf/ So after cleaning up my work i run rm -rf * in the woring folder.

Here is a small guide how to build you first plugin. Here om building some syco commands for controlling apache and glassfish server. the commands are run from our syco-chuck release commands center so for adding them to syco i can controll the script from sudo and do some extra test before starting and stopping the service. https://lifeandshell.com/posts/setup-syco-on-you-centos-box/ Tue, 18 Feb 2014 15:27:04 +0000 https://lifeandshell.com/posts/setup-syco-on-you-centos-box/ So if you care about security and stability you must have syco installed on your server. Read more about syco on the github project https://github.com/systemconsole Im staring to use syco not only production but also on my “Own” server. So more of you should really start using it and here is i guide for you to start using syco 1.

And to get alerts we use an sms gateway. The problem is that sometimes when we work we bring down and server and we get so many sms from icinga that you trow away you phone. So for bringing the sms cost down and to have not so many sms to you phone i build a small email blocking script. This will take the address of the sms and only send one sms / email every 5 min (can be set to anything). https://lifeandshell.com/posts/django-sending-email/ Tue, 04 Jun 2013 21:35:24 +0000 https://lifeandshell.com/posts/django-sending-email/ building and small webpage and in that page I want an small contact field.
