denv-extract

Overview

denv-extract is a CLI that list or extract environment variables from a docker container.

You can see a demo here

You can connect to a remote server using the --server flag and using ssh url like ssh://user@host.

How to install

Run the following command: go install github.com/polivera/denv-extract@latest

Make sure that $GOPATH/bin is in your PATH

Commands

• list command example:

denv-extract list <search_criteria> [--server ssh://user@host]

List all the environment variables from a container (without value)

• all command example:

denv-extract all <search_criteria> [--server ssh://user@host]

Write all the container environment variables to a .env file (with value)

• select command example:

denv-extract select <search_criteria> [--server ssh://user@host]

Show a list of variables for the user to select. Those variables will be stored in a .env file (with value)

• fromFile command example:

denv-extract fromFile -f <path/to/file> <search_criteria> [--server ssh://user@host]

Given an incomplete environment file it will generate a .env file with the values from the container. If the value is already set in the input file, it will leave it as it is.

Known issues

• If the ssh connection requires prompt (either because of first connect of because of OTP authentication) the app will hang
• I just test this 3 times so I'm sure it will be a lot more :)
