# Environment

> 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:
```bash
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

```bash
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)

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

## Terminate

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

## Clone

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

## Swap URLs (Blue/Green)

```bash
eb swap <env1> --destination_name <env2>
```

## Abort In-Progress Update

```bash
eb abort
```

## Restore Terminated Environment

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

---

## Composability

- **Deploy to new environment**: Use `deploy` skill
- **Configure new environment**: Use `config` skill
- **Check environment status**: Use `status` skill
- **Platform migration**: Use `maintenance` skill
