Building Docker image with Packer and provisioning with Ansible

Overview

Packer

• Packer is used to build image from a base image, perform provisions and store (commit) the final image.

• We use provisioners and Packer templates to do the actual work to create the final image.

• We use Ansible for provisioning.

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

#!/bin/bash

readonly DB_FILE="$(pwd)/images.db"
readonly IMG_DIR="$(pwd)/images"

save-images() {
  echo "Create ${DB_FILE}"
  echo "$(docker images|grep -v 'IMAGE ID'|awk '{printf("%s %s %s\n", $1, $2, $3)}'|column -t)" > "${DB_FILE}"
  
  echo "Read ${DB_FILE}"

In redhat, if you need build container from base image, for example, registry.access.redhat.com/rhel7/rhel:7.3-53 (free download from https://access.redhat.com/containers) You have to build this image on a red hat server with subscription managed registered.

Here is the way to bypass the check and you can build docker image on any redhat 7 server.

make sure the package has been installed

yum install rh-amazon-rhui-client

list the package files

# By default, Docker containers run as the root user. This is bad because:
#   1) You're more likely to modify up settings that you shouldn't be
#   2) If an attacker gets access to your container - well, that's bad if they're root.
# Here's how you can run change a Docker container to run as a non-root user

## CREATE APP USER ##

# Create the home directory for the new app user.
RUN mkdir -p /home/app
