Create a new Docker volume and fill it with local data

Create Docker volume

When moving from a local development environment to the cloud, e.g. Docker swarm or Kubernetes, you often need a way to access local files. However, in the cloud your local file system cannot be accessed anymore, so you need a way to copy your local files to a volume and mount that instead. This is the purpose of the script. You supply it with the volume name (e.g. schemas) and the local folder containing the schemas, e.g. ../../schemas, and a schemas volume is created, containing all data that is copied into the container.

./create_volume.sh schemas ../../schemas

Add SSH site to Windows Terminal

Source.

You can use a commandline field in your profile configuration to initiate an SSH connection on tab creation.

Step-by-step guide:

  1. Open Settings (Ctrl+,)
  2. Find the "list" array in the "profiles" object
  3. Duplicate a Command Prompt profile ("commandline": "cmd.exe")
  4. Change the commandline value to: ssh me@my-server -p 22 -i ~/.ssh/id_rsa (use your own connection command).

EADDRINUSE error

EADDRINUSE error (Endpoint Address In Use)

Error: listen EADDRINUSE: address already in use :::1234

When node.js complains that an address is in use, this may happen because the service did not end properly. In order to kill the hanging process, do the following in an Admin PowerShell window:

netstat -ano|findstr "PID :1234"
