download https://rtyley.github.io/bfg-repo-cleaner/

clone `git clone --mirror git://example.com/some-repo.git`

if your files to delete are in the last "master" commit, delete the file and push 
.   
The last master commit is always preserved so you need to make another commit.

then `bfg --delete-files filename.txt  my-repo.git`
my-repo.git is the name in your folder

Create a LightSail instance
During creation, remember to change the region
when using a specific region a private key will be created

download the key
you can use the `ssh -i path/to/key user@host`
or you can add the private key (without the .pem extension) inside your .ssh folder, then
edit the config file with the user, url and path to the private key

to copy a file into lightsail, do not log into ssh, but use `scp /path/to/file user@host:./path/where/to/copy`
