Azure provides a cloud shell with Terraform already installed and even an editor aware of Terraform source. I tested creating a network and VM using the cloud shell in the browser. REF: https://docs.microsoft.com/en-us/azure/virtual-machines/linux/terraform-install-configure Note: I am not showing dry run (terraform plan) but you should always be in the habit…
AWS Systems Manager and State Manager
I have used different configuration management tools for different use cases in the past. I liked how puppet had a central server and clients pull on a schedule. This way continuous control can be asserted. Ansible on the other hand is much simpler to use and works better during provisioning.…
Test Tcp Open Port
If you don’t have telnet or nc installed and want to quickly test firewall traffic to a server and specific port you can try this. It needs a new enough bash but still pretty quick and handy. Good test port is open Port not open Good test port is open…
Sudo and home folder
I suspect behavior of setting $HOME when using sudo may differ between Linux flavors. As most modern Unix operating systems discourage using the root account and promote using sudo, I have mostly always used “sudo -s”. I expect that my shell then will reference /root as my home folder($HOME). I…
Go Format Output Column Style
Similar to this article (using python) https://blog.ls-al.com/python-output-align-by-column/ I also did a quick Golang implementation. It is not quite as done as I would like but it is reasonably close. Similar to the python article the idea is to use something like an array to store column header descriptions and a…
Go Associative Array
Jotting down my test to implement an associative array similar to as my python test here: https://blog.ls-al.com/python-dict-for-arrays/ In python I used dict and in go I used map. Output
Restic updates
If you are used to the way how easy rclone updates with a one-liner then this may help with restic also. Found it here: https://github.com/restic/restic/issues/1930 “just wanted to share a simple 4-line script to download and install the latest release of restic from Linux shell using cURL to /usr/local/bin:”
Object Storage with Duplicity and Rclone
At this point I prefer using restic for my object storage backup needs but since I did a POC for duplicity and specifically using rclone with duplicity I am writing down my notes. A good description of duplicity and restic here: Backing Up Linux to Backblaze B2 with Duplicity and…
Object Storage with Restic and Rclone
I have been playing around with some options to utilize Object Storage for backups. Since I am working on Oracle Cloud Infrastructure (OCI) I am doing my POC using the OCI Object Storage. OCI object storage does have Swift and S3 Compatibility API’s to interface with. Of course if you…
Bash Date Usage For Naming
I am recording some scripting I used to create backup classification/retention naming. It can be simplified into one function easily but I kept it like this so I can copy and paste easier which function I need. Script is pretty self explanatory but basically it takes today’s date and name…
