Managing dynamic inventory in private subnets using bastion jump box The title of post is quite large, but is something I encountered issues in the last weeks. I had a VPC in AWS, creating x amount of instances in a private network, and was quite complex to manage this instance using static inventory files. So I will explain you how to manage this problem with Ansible . Before continue, I want to say these articles are really good and can help you with this issues. Dynamic inventory Ansible (behind a jumpbox / bastion ) SSH jump hosts on CircleCI 2.0 So you will be asking, if these articles are so good, why are you writing them again? Easy, I’m doing this in Gitlab CI, and I suppose other CI will encounter similar issues. It’s not possible to connect to the instances using the instructions above. First Step We get our inventory in a dynamic way. For this we will use the inventory scripts. We need to modify the ec2.ini file with uncommenting the vpc...

This is a small post about how to use inventory plugins in Ansible. If you are looking the script way I recommend to read this article: http://gloriasilveira.com/setting-up-ansible-for-aws-with-dynamic-inventory-ec2.html It explains really good this or you can watch this video: https://www.youtube.com/watch?v=LnbqO1kTPqE&t=6s But if you’re looking to use inventory this article can help you. First of all, why should I used inventory if all over the internet they’re using the python scripts? Well, Ansible recommends it: Inventory plugins take advantage of the most recent updates to Ansible’s core code. We recommend plugins over scripts for dynamic inventory. You can write your own plugin to connect to additional dynamic inventory sources. https://docs.ansible.com/ansible/latest/user_guide/intro_dynamic_inventory.html The actual ansible guide is quite good, but there was a step that got me confused, probably my english isn’t so good and I didn’t understood it. We need to ena...

I encounter with this issue how to make possible to display my GIT branch in the console. I found the answer in ASK UBUNTU:  https://askubuntu.com/questions/730754/how-do-i-show-the-git-branch-with-colours-in-bash-prompt Step 1 nano ~/. bashrc Step 2 Add the following code at the end of the line # Show git branch name force_color_prompt = yes color_prompt = yes parse_git_branch () { git branch 2 > / dev / null | sed - e '/^[^*]/d' - e 's/* \(.*\)/(\1)/' } if [ "$color_prompt" = yes ]; then PS1 = '${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ ' else PS1 = '${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ ' fi unset color_prompt force_color_prompt Step 3 Reload the file source ~/. bashrc

I have been working with AWS in the last days and encounter some issues when using RDS.  Generally when you're working in development environment you have setup your database as Publicly accessible and this isn't an issue. But when you're working in Production. So we place the Amazon RDS database into a private subnet. What we need to do for connecting to the database using PgAdmin or other tool? We're going to use one of the most common methods for doing this. You will need to launch an Amazon EC2 instance in the public subnet and then use it as jumping box. So after you have your EC2, you will need to run the following command. See explantion below After this, you will need to configure your PgAdmin. The host name will be your localhost, the port is the same you define in the above command. Maintenance database will be your DB name and the username you have for connecting. Hope this helps you connect to your databases.

I have been working with docker in the last days, and encounter the syntax issue with gedit. Just pure plain text. So make a small search and found an easy way for fixing this. I found Jasper J.F. van den Bosch repository in GitHub and found the solution for this simple problem. We need to download the docker.lang file, available here:  https://github.com/ilogue/docker.lang/blob/master/docker.lang After that, you go to the folder you save the file and do the following command. sudo mv docker.lang /usr/share/gtksourceview-3.0/language-specs/  If this doesn't work you can try the following: sudo mv docker.lang  ~/.local/share/gtksourceview-3.0/language-specs/ And that's all!

So I decided to give it a try to Zsh I really like the way it shows me the information at CLI and really useful when using git. I didn't have to many issues for installing it.
