UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker
now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.
Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

First of all, please note that token expiration and revoking are two different things.
A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work. | |
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0." | |
Database files have to be updated before starting the server, here are the steps that had to be followed: | |
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default | |
brew unlink postgresql | |
brew install postgresql@9.6 | |
brew unlink postgresql@9.6 | |
brew link postgresql |
Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.
Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.
This method does not add your OAuth token to Gemfile.lock
. It uses bundle config to store your credentials, and allows you to configure Heroku to use environment variables when deploying.
