Why can't the CLI generate the config if I can see all the accounts and roles in the SSO start page? That's a desperately needed feature.

I would love to see a browser extension for SSO account tabs if AWS can't solve it natively.

Depending on your SSO provider, you can list all the roles using saml2aws[0] and then parse the output so you can generate the relavant config. It is a bit tedious, but it works.

`aws configure sso` does that, but:

1 - You need to do that with each account / role pair

2 - It gives profiles very long names by default (<role>-<account_number>)

3 - It does not set $AWS_PROFILE, so you need to pass `<...> --profile <...>` manually

So the code is actually there already, they just need to make the experience better.

I imagine most are like me and after doing this once or twice falls back to a text editor.

Another complaint I have is that afaik none of the SDKs have any kind of API for SSO login.

Synchronizing ~/aws/config gets harder and harder as your team grows because there are both more people who need to receive changes and more people making changes.

I think the human-readable names for AWS accounts need to be part of the account, not part of the laptop. Substrate [1] does this so that you can type commands like `substrate assume-role -domain example -environment production -quality beta` [2] to get where you're going.

One place I worked just committed it to the git repo (obviously just SSO and account numbers, no passwords or tokens)

I have thought a great deal about whether I also want EKS clusters to officially support nodes in multiple AWS accounts. On the one hand, having the option to create that additional low-level isolation would be lovely, even and maybe even especially if I didn't always take it. On the other hand, isolating two things from each other but then tying them to the same Kubernetes cluster upgrade schedule feels wrong.

In the end, I decided that if I care about isolating two things enough to put them in separate AWS accounts, I'm willing to spend the $75 per month that it takes to have separate EKS clusters, too. (This opinion perhaps obviously doesn't fit will with hobby/side project budgets.)

> My current solution is to share my ~/aws/config with everyone so we all have the same profile names and scripts can work for everyone.

If you're on Mac/Linux you could have everyone use direnv. Add a .envrc file in each git repo (or your script's subdirectory) with `export AWS_PROFILE=profilename`. Now everyone is working with the same profile names without having to pass around config files.

Just in case, can be used in WSL too, if one is on Windows

One hidden gotcha about RAM-shared VPCs is that some services (cough RabbitMQ cough) don’t work in them.
