AWS has introduced Lightsail (https://aws NULL.amazon NULL.com/lightsail/) to compete with Digital Ocean, Linode, etc. for an inexpensive VPS (Virtual Private Server) offering.

In this article we will use Terraform (https://www NULL.terraform NULL.io/) (Infrastructure as Code) to swiftly bring up an AWS Lightsail instance in us-east-1 on a static IP, add a DNS Zone for the site in mention and install docker/docker-compose on it.

We will use ‘myweb’ as an example in this article, using the same base path of ‘dev’ that was previously created, the container-admin group, and using ~/.local/bin for the binary. Please modify for your own purposes.

Please use ‘Get started with Lightsail for free’ (https://portal NULL.aws NULL.amazon NULL.com/billing/signup?client=lightsail&fid=1A3F6B376ECAC516-2C15C39C5ACECACB&redirect_url=https%3A%2F%2Flightsail NULL.aws NULL.amazon NULL.com%2Fls%2Fsignup#/start) prior to commencing with this article.

–>
Go in to the dev directory/link located within your home directory:

$ cd ~/dev

Grab Terraform:

$ wget https://releases.hashicorp.com/terraform/0.12.9/terraform_0.12.9_linux_amd64.zip

Install Unzip if you do not have it installed:

$ sudo apt -y install unzip

Unzip it:

$ unzip terraform_0.12.9_linux_amd64.zip

Move it:

$ mv terraform ~/.local/bin && chmod 754 ~/.local/bin/terraform

Create a work folder:

$ mkdir -p terraform/myweb/scripts && cd terraform/myweb

Add an IAM Policy to the container-admin group so it will have access to the Lightsail API:
AWS UI Console -> Services -> Security, Identity, & Compliance -> IAM -> Policies -> Create Policy -> JSON (replace <AWS ACCOUNT ID> in the Resource arn with your Account’s ID (shown under the top right drop-down (of your name) within the My Account page next to the Account Id: under Account Settings)):

Review Policy ->

Name: AllowLightsail
Description: Allow access to Lightsail.

Create Policy.

Groups -> container-admin -> Attach Policy -> Search for AllowLightsail -> Attach Policy.

Generate an SSH Key Pair:

$ ssh-keygen -q -t rsa -b 2048 -N '' -f ~/.ssh/myweb && chmod 400 ~/.ssh/myweb

Upgrade the AWS CLI on your host:

$ pip3 install awscli --upgrade --user && chmod 754 ~/.local/bin/aws

Import the public key to Lightsail:

$ aws lightsail import-key-pair --key-pair-name myweb --public-key-base64 file://~/.ssh/myweb.pub

Set the version to greater then or equal to 2.0, interpolate the region and use the AWS CLI credentials file:

$ cat << 'EOF' > provider.tf
> provider "aws" {
>         version                         = ">= 2.0"
>
>         region                          = "${var.region}"
>         shared_credentials_file         = "~/.aws/credentials"
> }
> EOF

Set the default region as a variable:

$ cat << 'EOF' > vars.tf
> variable "region" {
>         default = "us-east-1"
> }
> EOF

Create a Lightsail DNS Zone of myweb.com, allocate a static IP for it, create a nano instance based off of Ubuntu 18_04, reference an extraneous file for user_data (run once script on Virtual Machine boot), tag it and attach the allocated Static IP to it:

$ cat << 'EOF' > lightsail.tf
> resource "aws_lightsail_domain" "myweb" {
>         domain_name = "myweb.com"
> }
>
> resource "aws_lightsail_static_ip" "myweb" {
>         name = "static-ip_myweb"
> }
>
> resource "aws_lightsail_instance" "myweb" {
>         name                    = "site_myweb"
>         availability_zone       = "${var.region}a"
>         blueprint_id            = "ubuntu_18_04"
>         bundle_id               = "nano_2_0"
>         key_pair_name           = "myweb"
>         user_data               = "${data.template_file.init_script.rendered}"
>         tags    = {
>                Site = "myweb.com"
>         }
> }

>        instance_name  = "${aws_lightsail_instance.myweb.name}"
> }
> EOF

Output our allocated and attached static IP after creation:

$ cat << 'EOF' > output.tf
> output "static_public_ip" {
>        value = "${aws_lightsail_static_ip.myweb.ip_address}"
> }
> EOF

Create a template file to reference a run-once on boot user_data script:

$ cat << 'EOF' > install.tf
> data "template_file" "init_script" {
>        template = "${file("scripts/install.sh")}"
> }
> EOF

Create the shell script for user_data:

$ cat << 'EOF' > scripts/install.sh
> #!/bin/bash
>
> MY_HOME="/home/ubuntu"
> export DEBIAN_FRONTEND=noninteractive
>
> # Install prereqs
> apt update

> su ubuntu -c "mkdir -p $MY_HOME/.local/bin"
> su ubuntu -c "pip3 install docker-compose --upgrade --user && chmod 754 $MY_HOME/.local/bin/docker-compose"
> usermod -aG docker ubuntu
> # Add PATH
> printf "\nexport PATH=\$PATH:$MY_HOME/.local/bin\n" >> $MY_HOME/.bashrc
>
> exit 0
> EOF

Initialize the directory:

$ terraform init

Run a dry-run to see what will occur:

$ terraform plan

Provision:

$ terraform apply --auto-approve

Log on to the instance (please wait ~30 seconds for the static ip to attach to the instance):

$ ssh -i ~/.ssh/myweb ubuntu@<The value of static_public_ip that was reported.  One can also use 'terraform output static_public_ip' to print it again.>

Type yes and hit enter to accept.

On the host (please wait a short while for the run-once script to complete):

$ docker --version
$ docker-compose --version
$ logout

Tear down what was created:

$ terraform destroy

In this article we will use docker compose to spin up two containers. One will run a web server (Nginx) and one will run php-fpm (Hypertext Preprocessor FastCGI Process Manager). All requests for .php will be forwarded on to the php-fpm service for processing which is running in a separate container and be presented by Nginx. We will use images based off of Alpine (https://alpinelinux NULL.org) which is a minimal Linux environment with a small footprint.

–>
Change directory in to the dev/docker path located within your home directory:

$ cd ~/dev/docker

Create a directory called myweb and go in to it:

$ mkdir myweb && cd myweb

Create five directories called nginx, nginx/conf, php-fpm, src and src/web:

$ mkdir -p nginx/conf php-fpm -p src/web

Create a docker-compose.yml file like so:

$ cat << 'EOF' > docker-compose.yml
> version: '3'
>
> services:
>     nginx:
>         image: myweb-nginx:v1
>         build: ./nginx
>         volumes:
>             - ./src/web:/var/www/html
>         ports:
>             - 80:80
>         depends_on:
>             - php-fpm
>
>     php-fpm:
>         image: myweb-php-fpm:v1
>         build: ./php-fpm
>         volumes:
>             - ./src/web:/var/www/html
> EOF

This sets the version to 3 for docker-compose and sets up two services called nginx and php-fpm. It will build what is inside each folder, overlay src/web in to them (so you can work independently on the content without rebuilding the container) and map port 80 (HTTP) to the inside HTTP/80 port. Nginx requires php-fpm so you denote that with a depends_on; this service will start first. The ‘image:’ will name and tag this accordingly on the docker images.

Create a Dockerfile inside nginx:

$ cat << 'EOF' > nginx/Dockerfile
> FROM nginx:stable-alpine
> COPY ./conf/default.conf /etc/nginx/conf.d
> EOF

Create a default.conf inside nginx/conf:

$ cat << 'EOF' > nginx/conf/default.conf
> server {
>    index index.php;
>    server_name "";
>    error_log /var/log/nginx/error.log;
>    access_log /var/log/nginx/access.log;
>    root /var/www/html;
>
>    location ~\.php$ {
>        try_files $uri =404;
>        fastcgi_split_path_info ^(.+.php)(/.+)$;
>        fastcgi_pass php-fpm:9000;
>        fastcgi_index index.php;
>        include fastcgi_params;
>        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
>        fastcgi_param PATH_INFO $fastcgi_path_info;
>    }
> }
> EOF

This will pull the stable Nginx docker image based off of Alpine and copy our default.conf in to the container. The default.conf sets up the web server to forward .php over to our container which is called ‘php-fpm’ on the default port of 9000 and sets the default index page as index.php.

Create a Dockerfile inside php-fpm:

$ cat << 'EOF' > php-fpm/Dockerfile
> FROM php:7.3-fpm-alpine
> EOF

This will pull the php-fpm 7.3 docker image based off of Alpine.

Create a index.php in src/web:

$ cat << 'EOF' > src/web/index.php
> <html>
>  <head>
>   <title>Hello World - PHP Test</title>
>  </head>
>  <body>
>   <?php echo '<p>Hello World</p>'; ?>
>  </body>
> </html>
> EOF

Now build both containers/launch both services and send in to non-interactive mode:

$ docker-compose up -d

Now use curl to make a request:

$ curl http://localhost

You should see:

<html>
 <head>
  <title>Hello World - PHP Test</title>
 </head>
 <body>
  <p>Hello World</p>
 </body>
</html>

You can see the containers running by typing:

$ docker ps

You can list the containers:

$ docker container ls

You can stop the containers:

$ docker-compose stop

You can remove the containers:

$ docker-compose down

You can list the images:

$ docker images

Technology that we will work with are Kubernetes (AWS EKS (Elastic Kubernetes Service)/Azure AKS (Azure Kubernetes Service) ) and Docker (AWS ECR (Elastic Container Registry)/Azure ACR (Azure Container Registry) ).

Kubernetes (https://kubernetes NULL.io/) allows for management of containers to provide scalability, high availability and fault tolerance among others. Containers (https://www NULL.docker NULL.com/) are isolated packages/images, that contain all that is needed to run an application. They are lightweight, portable and ensures runtime is consistent.

The below was written using Ubuntu 18.04.2-LTS (http://releases NULL.ubuntu NULL.com/18 NULL.04/) Desktop (minimal) and Windows Subsystem (Windows 10 Insider (https://insider NULL.windows NULL.com/en-us/) Preview; 18950.1000 (Fast Ring); 18362.267 (May 2019 Update (https://support NULL.microsoft NULL.com/en-us/help/4505903/windows-10-update-kb4505903))) for Linux (WSL2 and WSL1; Ubuntu). It should be applicable to Debian, Ubuntu Docker (lsb-release package has been left in to accommodate) and will be applicable to any Fast Ring Windows 10 build >= 18917.

Note: Any build lower then 18917, should use Docker Desktop and use the .exe commands in WSL via named pipes.

If you are using Windows 10 Home or any non Windows based 10 build, then please use Vagrant (https://www NULL.vagrantup NULL.com) (non-Windows 10) to spin up a Virtual Machine or Docker Toolbox (https://docs NULL.docker NULL.com/toolbox/) (Windows 10 Home in conjunction with WSL).

Windows 10:
Start -> Control Panel -> Programs and Features -> Turn Windows features on or off -> Select Windows Subsystem for Linux -> ok -> Restart now.

Open a Browser -> WSL Store (https://aka NULL.ms/wslstore) -> Open Microsoft Store -> Ubuntu -> Get -> Launch or Start -> Search for programs and files -> Ubuntu (with the colored circular icon and hit enter) -> Installing, this may take a few minutes… -> Enter new UNIX username: -> Enter new UNIX password: -> Retype new UNIX password: -> Right click the command window (on the toolbar) -> Options -> Quick Edit Mode -> ok
<–

–>
Not for Windows 10 builds < 18917

$ logout

Start -> Search for powershell -> right click -> Run as administrator and select Yes to the Elevated UAC prompt)
PS > Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform

Select Reboot (default) when prompted.

Convert Ubuntu to WSL2:
Start -> Run: cmd

To see what Distros are installed, state and version:

> wsl -l -v 

Set WSL2 on the distribution:

> wsl --set-version Ubuntu 2 

Note: This will take a while.

After it is finished, run the command, 2 lines above (which was used to list) to see that it is now Version 2.

Start -> Search for programs and files -> Ubuntu (with the colored circular icon and hit enter)

Install some prerequisites:
Note: software-properties-common isn’t needed if not installing docker (Windows 10 (WSL) builds < 18917).

$ sudo apt update
$ sudo apt install -y python3-pip apt-transport-https ca-certificates curl gnupg2 lsb-release software-properties-common

–>
Restart services during package upgrades without asking? -> Tab to <Yes> and hit Enter.

Install AWS CLI:

$ pip3 install awscli --upgrade --user && chmod 754 ~/.local/bin/aws

Install EKSCTL (weaveworks):

$ curl --silent --location "https://github.com/weaveworks/eksctl/releases/download/latest_release/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C ~/.local/bin && chmod 754 ~/.local/bin/eksctl

Install KUBECTL:

$ curl -o ~/.local/bin/kubectl --silent -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod 754 ~/.local/bin/kubectl

Install Docker:

–>
Not for Windows 10 (WSL) < 18917.

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
$ sudo apt update
$ sudo apt install -y docker-ce

Show the status of docker (it should be enabled and running; if not then perform an ‘enable’ and ‘start’ (without the ‘| grep …’):

–>
Not for Windows 10 (WSL).

$ systemctl status docker | grep -i "loaded\|active"

<–

–>
For Windows 10 (WSL (>=18917)).

Start and show the status of docker:

$ sudo service docker start
$ sudo service docker status

It should come up in to a running state.

Note: This will stay running as a background task when WSL is closed, however when the host is rebooted/user session is logged out of, it will need to be launched again once opening WSL. This section will be updated on how to have this start when the host boots at a later time.
<–

Install Docker Compose:

–>
Not for Windows 10 (WSL) < 18917.

$ pip3 install docker-compose --upgrade --user && chmod 754 ~/.local/bin/docker-compose

Allow your user the right to execute docker without sudo:

$ sudo usermod -aG docker $USER
$ logout

Log back in to a shell.

Create a work folder, inside your home directory:

$ mkdir -p dev/docker

<–

–>
For Windows 10 builds < 18917

Start -> Control Panel -> Programs and Features -> Turn Windows features on or off -> Select Hyper-V and Containers -> ok -> Restart now.

Install Docker Desktop (https://download NULL.docker NULL.com/win/stable/Docker%20for%20Windows%20Installer NULL.exe) -> Leave Defaults -> Log out and back in -> System Tray should show it Launching to a Run state.

Click System Tray -> Settings -> Shared Drives -> Select C -> Apply -> Type in your Windows user’s password to confirm -> close out of settings

Launch the WSL shell.

Create a work folder inside the Windows mount, symbolic link it within your home directory inside WSL and alias the .exe with the bare commands for docker/docker-compose and add for permanence:

$ mkdir -p /mnt/c/dev/docker
$ ln -s /mnt/c/dev dev
$ cat << EOF >> ~/.bashrc
>
> alias docker=docker.exe
> alias docker-compose=docker-compose.exe
> EOF
$ alias docker=docker.exe
$ alias docker-compose=docker-compose.exe

<–

Install Azure CLI:

$ curl -sL https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/microsoft.asc.gpg 1>/dev/null
$ echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/azure-cli.list
$ sudo apt update
$ sudo apt install -y azure-cli

Add .local/bin located in your HOME Directory in to your PATH for permanence:

$ cat << 'EOF' >> ~/.bashrc
>
> export PATH=$PATH:~/.local/bin
> EOF
$ export PATH=$PATH:~/.local/bin 

Ensure version output is shown:

$ aws --version
$ eksctl version
$ kubectl version 2>/dev/null
$ docker --version
$ docker-compose --version
$ az --version

DEVOPS?!

While not a new concept, it being labelled as such are recent and the methodologies have been adjusted/updated as well.

Perhaps you have a background such as myself, coming from the old-world where one was performing these responsibilities using custom shell scripts, proprietary Content Management/Versioning Systems, raw shared mounts to promote/copy to stages, deploying templated systems on to server farms by hand, etc. These days, there are a lot of tools and systems available to streamline these processes.

Gone are the days of having rigid compartmentalization and what has risen are Developers performing Operations and Operations performing Development. This creates a cohesive unit to get things prim and proper at an accelerated rate, before landing in to Production. Attaining minimalism is a goal to strive for

In this section I take you through my up-skill and assimilation in to ‘modern’ Development Operations as it pertains to the Cloud platform/framework.
