mysqldump(1) command. It is designed to be run as an AWS Lambda function and
load config from Parameter Store.
## Test
```

```
## Build
```
docker build -t mysql_export src
docker run --rm mysql_export cat /build/release.zip > build\release.zip
```
## Deploy
```
terraform apply -target=aws_lambda_function.mysql_export
```
## Config
```
aws ssm put-parameter \
--name /dev/env.json \
--type SecureString \
--value '{"MYSQL_USERNAME":"myapp","MYSQL_PASSWORD":"secret","MYSQL_HOSTNAME":"myapp-dev.rds.amazon.com","MYSQL_DATABASE":"myapp"}'
```
## Run
```
aws lambda invoke \
--function-name mysql_export \
--invocation-type RequestResponse \
--log-type Tail \
--payload '{"APP_ENV":"dev"}' \
result.json
```
