AWS¶

Profile Switching¶

`af` — Interactive Profile Switcher¶

The primary way to switch AWS profiles:

af

Presents all AWS profiles via fzf
Exports AWS_PROFILE
Checks if the session is valid (sts get-caller-identity)
If expired, triggers aws sso login
Displays account info on success

Quick Aliases¶

Alias	Action
`afc`	Clear all AWS env vars
`afp`	Print current AWS profile

CLI Aliases¶

Custom AWS CLI aliases are defined in ~/.aws/cli/alias:

Identity¶

aws whoami      # Quick: sts get-caller-identity
aws identity    # Full: identity in table format

Profiles¶

Parsed from ~/.aws/config, showing SSO account and role alongside each name:

aws profile-list             # name / sso_account_id / sso_role_name, aligned
aws profile-pick [query]     # same list through fzf, prints the name only
export AWS_PROFILE=$(aws profile-pick)

Use af to switch and handle SSO login - an aws alias runs in a subprocess and cannot change the current shell.

EKS¶

aws eks-list [region]                     # List clusters
aws eks-update [region]                   # Pick a cluster (fzf) and update kubeconfig

EKS_ROLE_ARN=$(aws role-pick eks) aws eks-update   # cross-account: kubectl assumes that role

Role Assumption¶

Shell functions (dot_config/zsh/functions/general.zsh), not CLI aliases: the credentials have to land in the current shell, and aws aliases run in a subprocess.

aws-assume                          # pick a role with fzf, export its credentials
aws-assume arn:aws:iam::123:role/X  # or pass the ARN
aws-unassume                        # drop the credentials, restore AWS_PROFILE

Max Pods Calculator¶

max-pods-calculator --instance-type m5.large --cni-version 1.12.0

Calculates the maximum number of pods for an EKS node based on instance type, CNI version, and prefix delegation settings.
