PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Kubernetes terminology:

1. Pods

• Group of containers, and is the smallest unit that Kubenetes adminsters. Pods have a single IP address that is applied to every container withiun the pod. ner.

2. Deployments

• Define the scale at which you want to run your application by letting you set the details of how you would like the pods replicated on your Kubenertes pods.

3. Services

• Kubernetes doesn’t treat its pods as unique, long-running instances; if a pod encounters an issue and dies, it’s Kubernetes’ job to replace it so that the application doesn’t experience any downtime.
