Infrastructure

Beet comes with ansstconfiguration for managing infrastructure.

beet infra

This command is a lightweight wrapper ofnpx sst, with some added conventions.

infra directory

Rust is currently not well supported in sst, for example it refuses to deploy without building a binary, but doesnt allow feature flags etc. The infra directory has some hacks to get around this, providing a dummyCargo.tomlandbootstrapfile. For this reasonbeet infrawill cd into the infra directory for all sst commands.

default stages

Beet will default to thedevstage, usingbeet infra --releasewill use theprodstage instead.

Tips

SST is a great tool, but does take some practice to build up an intuition for how IaC works.

Dangling Resources

Its important to callbeet infra removebefore editing thesst.config.tsfile to avoid resources not being cleaned up. Also I'd recommend not interrupting an sst command.

State Mismatch

Running sst commands will keep a local record of the state of the application infrastructure. If these become out of sync, for example if a resource is manually created or removed,sst deploywill error. This can be fixed withbeet infra refresh

Custom Domains

sst can hook up custom domains, this guide will use cloudflare which has an excellent reputation as a domain registrar.

1. Purchase a domain athttps://domains.cloudflare.com/
2. Configure the cloudflare environment variables:
   • CLOUDFLARE_DEFAULT_ACCOUNT_ID: https://dash.cloudflare.com/login > 'Bobs Account' hamburger > Copy Account ID
   • CLOUDFLARE_API_TOKEN: https://dash.cloudflare.com/profile/api-tokens > Create Token > edit zone DNS > specify zone (recommended)> Continue To Summary > Create Token > Copy
3. Update thesst.config.ts, seethis site's configfor an example
4. Runbeet infra

AWS Credentials

AWS credentials are required for sst and cargo-lambda:

1. IAM -> User Groups -> Create Group:sst-admin-> Create
2. Permissions -> Add Permissions -> Create Inline Policy
3. Copy below -> next -> name:sst-recommended-policy
4. Users -> Create User ->my-computer-name-sst-deploy-> Next
5. User Groups -> Addsst-admin-> Next -> Create User
6. Users ->my-computer-name-sst-deploy-> Security Credentials -> Access Keys -> Create Access Key
7. In the cliaws configure, copy-paste Access Key ID & Secret
