Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

With the latest version of Docker for Mac and Windows (18.06), you can prefix all your mvn commands by RUN --mount=target=/root/.m2,type=cache:

Example:

# syntax = tonistiigi/dockerfile:runmount20180618
FROM maven:3.5-jdk-8-alpine AS build
COPY . .
RUN --mount=target=/root/.m2,type=cache mvn --batch-mode clean compile assembly:single

FROM openjdk:8-jre-alpine3.7

Fetching artifact programmatically through REST/API

Nexus 2.x

Nexus 2.x had a REST API to download artifacts like below based on some Maven GAV co-ordinates but this no longer works for Nexus 3.x

wget "http://local:8081/service/local/artifact/maven/redirect?g=com.mycompany&a=my-app&v=LATEST" --content-disposition

or

curl --insecure "https://local:8081/service/local/artifact/maven/content?r=public&g=log4j&a=log4j&v=1.2.17&p=jar&c=" > log4j.jar
