Using CloudFlare to Validate DNS For An ACM Certificate
I recently received a notification from AWS indicating that ACM certificates I had in place for some S3 buckets I expose for websites could not renew due to an inability to validate via DNS.
Figuring out how to make it work was non-trivial, so I'm writing it up so I can remember in the future, and maybe save somebody else some trouble, as everything I found had to do with auto-provisioning via Terraform.
Copy A File From A Docker Container to the Host
Occasionally, I want to get a file from a Docker container back to the host system.
First, you need to get the container ID; you can do this using docker ps.
Once you have that, use, docker cp as follows:
docker cp <containerId>:/path/to/file/in/container path/on/host
