Configure DDEV for AWS CLI, and use an EC2 instance as a jumphost

.gitignore

# Add the following to  your project's .gitignore
# The approach here assumes you're going to want to have the awscli also configured
# on your host OS, so we can just copy configs from ~/.aws/ on your host OS into the
# ddev web container during startup by way of the .ddev/homeadditions folder.

jumphost.yaml

# Add the following in .ddev/providers/jumphost.yaml

# Example AWS jumphost rsync provider configuration.

# This will pull a database and files from a network location via an AWS
# jumphost. It operates inside the web container and uses ssh, so you need
# to `ddev auth ssh` first.

# To use this configuration,
#
# 1. You need a database dump and/or user-generated files tarball that you
#    have access to somewhere on the internet
# 2. Copy jumphost.yaml.example to jumphost.yaml (or name it as you see fit)
# 3. `ddev auth ssh` (only needs to be done once per ddev session or reboot)
# 4. Use `ddev pull jumphost` to pull the project database and files.

# Note that while this is done in the web container it could also be done on
# the host, and then you wouldn't need the `ddev auth ssh`
