AWS CLI tools, vim tips, and a new blogging setup!

aws-sso-cli

https://github.com/synfinatic/aws-sso-cli. Provides some convenience commands for working with AWS SSO roles at the command line.

Notes:

installed deb into my WSL ubuntu environment via dpkg; possible to just download binary b/c it’s written in Go.
Sets itself up via wizard by running aws-sso with no arguments after installation.
“Open” UrlAction doesn’t work in WSL because no xdg-open command; use the “Print” action instead and paste into browser.
Use aws-sso cache to force reload of list of roles. It’ll have you open browser and confirm.
aws-sso list to list roles available
eval $(aws-sso eval -A <account id> -R <role name>) to export AWS-related env vars in bash. Really handy!

aws-shell

Not compatible with awscli v2! Instead just upgrade to the latest awscli v2 version for a nice auto-complete experience (see below)

awscli autocompletion

If you have latest awscli installed, run aws --cli-auto-prompt to enter an autocomplete mode. Documentation: https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-parameters-prompting.html

Avoid having to type --cli-auto-prompt every time by exporting AWS_CLI_AUTO_PROMPT=on and then just run aws (and hit enter) and you’ll end up in autoprompt mode!

Find unique records in vim

You don’t have to use the shell! Vim has a built-in :sort u that will sort all lines in a file and remote duplicates. Run :help :sort for details.

Played around with Jekyll and Netlify!

Preparing to re-launch my blog with Jekyll, I ran through the Jekyll tutorial and published the result to Netlify! Notes along the way:

I used Docker to run Jekyll locally rather than try to install it. Unfortunately when running jekyll serve in a Docker container inside WSL, the port wasn’t accessible from a Windows browser. So instead I just ran the Docker container from Powershell.
Auto-regeneration doesn’t seem to work in Windows however; have to manually restart the container to see changes. And it’s sloooow.
The sassc gem version 2.4.0 hangs on installation. A random StackOverflow post pointed me at installing 2.1.0 instead in my Gemfile.lock and that solved it. But that kind of thing shouldn’t be necessary.
Netlify is in fact totally amazing. No futzing with build configuration or even GitHub Actions; just point it at your GitHub repo (can even be a private repo) and as long as the right bits are in place (namely the Gemfile) it immediately creates a new site and does all the Jekyll build stuff automatically. It. Just. Works.
