tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

#!/usr/bin/env python

import os
import sys

from ansible.parsing.dataloader import DataLoader
from ansible.vars import VariableManager
from ansible.inventory import Inventory

I need a way to get a list of plugins so that I can use them with docker jenkins in the format <plugin>: <version>

1. get the jenkins cli.

The jenkins CLI will allow us to interact with our jenkins server from the command line. We can get it with a simple curl call.

curl 'localhost:8080/jnlpJars/jenkins-cli.jar' > jenkins-cli.jar

walkthrough: buildah on knative

The buildah utility is a versitile container build tool that does not require a daemon (everything is direct invocation). See my "deep dive" for a few hands on use-cases.

Recently knative was announced. It is a project to enable the kubernetes primitives needed to build a functions-as-a-service. There are a plumbing services needed around this use-case, "build" is one of them. Building containers is largely an indepenent goal and story of "serverless" or "FaaS", but I get why they are grouped together.
