Mysqldump from Docker container

docker exec -i mysql_container mysqldump -uroot -proot --databases database_name --skip-comments > /path/to/my/dump.sql

OBS

• This will generate a dump.sql file in your host machine. Awesome, eh?
• Avoid using --compact on your dump. This will make MySQL check your constraints which will cause troubles when reading your file (damm you MySQL). And don't use --force to fix this scenario: recreate your dump without --compact ¯_(ツ)_/¯

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.
