name	environment
description	Manages Elastic Beanstalk environment lifecycle including creation, termination, cloning, URL swapping, and blue/green deployments. Use when user says "eb create", "eb terminate", "eb clone", "eb swap", "new environment", "delete environment", "blue/green", "CNAME swap", "abort update", "restore environment", or "DNS availability". For deploying to an existing environment use deploy skill. For configuration changes use config skill.

Environment Management

Create, terminate, clone, swap, abort, and restore Elastic Beanstalk environments using the EB CLI.

When to Use

• Create a new environment
• Terminate an environment
• Clone an environment
• Swap URLs (blue/green deployment)
• Abort an in-progress update
• Restore a terminated environment
• Check DNS availability for CNAME

When NOT to Use

• Deploying to an existing environment → use deploy skill
• Changing configuration → use config skill
• Checking status → use status skill
• Platform updates → use maintenance skill

---

Destructive Operations Warning

Before terminate/restore: verify environment name, check traffic, confirm with user.

Solution Stack Validation

Before creating, verify the platform solution stack name:

aws elasticbeanstalk list-available-solution-stacks --output json --query 'SolutionStacks'

Solution stack name format (example — version will vary, always query for latest): 64bit Amazon Linux 2023 v<version> running Node.js <node-version>

Create Environment

eb create <env-name>
eb create <env-name> --instance_type t3.medium
eb create <env-name> --elb-type application
eb create <env-name> --single                    # No load balancer
eb create <env-name> --scale 2
eb create <env-name> --envvars KEY1=val1,KEY2=val2
eb create <env-name> --tags Env=production
eb create <env-name> --cname <prefix>
eb create <env-name> --tier worker

DNS Availability Check (before create with custom CNAME)

aws elasticbeanstalk check-dns-availability \
  --cname-prefix <desired-prefix> --output json

Terminate

eb terminate <env-name>
eb terminate <env-name> --force

Clone

eb clone <source-env> --clone_name <new-env>

Swap URLs (Blue/Green)

eb swap <env1> --destination_name <env2>

Abort In-Progress Update

eb abort

Restore Terminated Environment

eb restore --list
eb restore <env-id>
