You can create Stackery stacks for multiple accounts, which will be separated within the Stackery UI as different 'environments'.
To do so, add another account with
stackery setup-provider from within the Stackery CLI
If you see a message asking if you want to provision or overwrite, you're using an outdated version of the Stackery CLI and should update using 'stackery update'
version 1.4.3 or later will support multiple AWS accounts. Keep in mind that this tool won't work if the new AWS account you're adding is already associated with another Stackery account.
Once your agent is ready to go, enter
stackery setup-provider and enter the access key information. If you don't already have an access key, you can create in your AWS console under 'My Account>Security Credentials>Access Keys'
Once you've created a new key you can download a CSV copy or copy it from the AWS console (the AWS console will only display your key once, but you can download it for safe keeping)
enter your security key information into prompts. After that you'll select an AWS region.
While this region will be the default for new stacks, you're not tied to it permanently within stackery. You can set a different region for another stack via 'environments' or manage resources from anywhere by importing them via ARN.
you should see a final confirmation dialogue.
Now you can select this account as the 'environment' to deploy your stack.
