Usage

Once at least one profile is configured, you use ck-prism primarily through ck-prism login and the regular AWS CLI.

Log In

ck-prism login --profile production

On success, ck-prism:

1. Reuses the cached SSO token if it's still valid, otherwise refreshes it silently, or (as a last resort) opens your browser for a fresh SSO login.
2. Exchanges the token for temporary AWS credentials for the profile's role.
3. Writes the credentials to ~/.aws/credentials under the profile name, and the region/output to ~/.aws/config.
4. Prints how long the credentials are valid for.

Example output:

Using production profile
Exchanging token for AWS credentials...

AWS credentials written to ~/.aws/credentials
Credentials expire in 11 hours 59 minutes

Log In Without --profile

ck-prism login

ck-prism picks a profile for you based on this order:

1. If you have only one profile configured, it's used automatically.
2. Otherwise, you are shown a fuzzy-search picker with your profiles. The profile you used last time is pre-selected so you can just press Enter.

Every successful login records the profile used as the new "last profile", so repeated ck-prism login calls with Enter stay on the same profile until you pick a different one.

Use the AWS CLI

Once credentials are written, use aws as normal:

aws s3 ls --profile production
aws ec2 describe-instances --profile production

Or set it once for the shell:

export AWS_PROFILE=production
aws s3 ls

SDKs (Boto3, the AWS SDK for Go, Terraform's AWS provider, etc.) pick up the same profile from ~/.aws/credentials.

When Credentials Expire

AWS credentials issued by ck-prism are short-lived (typically around 12 hours). When they expire, just run ck-prism login again:

ck-prism login --profile production

If your SSO token is still valid, no browser opens. If it isn't, ck-prism will refresh it silently when possible, or open the browser for a fresh SSO login.

Token Caching

ck-prism caches SSO tokens on disk so you rarely need to open the browser. Tokens are stored per Prism tenant, not per profile, which means profiles sharing the same Prism domain and tenant also share a single SSO session. Logging into one profile satisfies the others on the same tenant until the SSO session itself expires.

In practice:

• First ck-prism login on a given Prism tenant opens the browser.
• Subsequent ck-prism login calls for any profile on the same tenant reuse that session, even across different AWS accounts and roles.
• Profiles on a different Prism tenant have their own independent session.

List Configured Profiles

ck-prism profiles list

Prints each profile name on its own line.

Remove a Profile

ck-prism profiles remove             # interactive picker + confirmation
ck-prism profiles remove staging -y  # by name, skip confirmation

See Configuration → Remove a Profile for what gets cleaned up.

Automatic Credential Refresh

Instead of running ck-prism login manually before each AWS command, you can have the AWS CLI fetch credentials from ck-prism on demand. When enabled for a profile, credentials live only in the AWS CLI's memory for each invocation and are never written to ~/.aws/credentials.

This is offered by default during ck-prism configure. To toggle it later, use:

ck-prism profiles enable-credential-process production
ck-prism profiles disable-credential-process production

Enabling updates ~/.aws/config with the right credential_process line and removes any static credentials for that profile from ~/.aws/credentials (otherwise the static entry would shadow it). Disabling reverts the change.

To enable it for every existing profile at once (useful if you have been using ck-prism for a while without it), run:

ck-prism profiles migrate-credential-process

This also repairs profiles that were already marked as enabled but whose ~/.aws/config entry is missing or out of date.

With automatic refresh on:

# No ck-prism login needed; the AWS CLI asks ck-prism for credentials as it needs them.
aws s3 ls --profile production
terraform plan

Running ck-prism login --profile production on a credential-process-enabled profile is a no-op and will print a reminder that no login is needed.

warning

Automatic refresh still needs a valid SSO session. The first time it runs in a new terminal session, or after the SSO token expires, ck-prism will try to open your browser. On headless machines (CI runners, SSH sessions without display forwarding), run ck-prism login --profile <name> interactively once to seed the token cache.

Shell Tab-Completion

ck-prism ships tab-completion for bash and zsh. Press Tab after ck-prism to cycle through commands, subcommands, and configured profile names.

Completions are installed automatically the first time you run ck-prism configure. If you need to (re)install them manually, or force a specific shell:

ck-prism setup-completions
ck-prism setup-completions --shell zsh   # force zsh even if the login shell is bash

Restart your terminal, or source the path printed by the command, to activate the new completions.
