Samples for AWS infra as a code

• aws-cli: frequent aws cli sample commands
• AWS-BJS
  • BJS-LAB1:phpdemo-full Build a full PHP Demo stack from zero in AWS BJS(China) region
  • BJS-LAB2:vpcfull-s3backend Here we demo how to build a solid vpc environment with HA NAT instances in AWS BJS(China) region, besides, we will show a new way to store terraform state(terraform managed aws resource state) in AWS s3 bucket
  • BJS-LAB3: This lab demos you a situation that, you have built a VPC environment just like BJS-LAB2, then you want to creat a PHP/MySQL app within it, then you can get the vpc details from stored S3 terraform state file
• ECS-DevOps
  • One HelloWorld service running on ECS cluster
  • CodePipeline for souce build/deploy , it supports In Place and Canary deployment module
• Spring-ECS
  • Total 4 Pet Clinic Micro Services, including Owner, Pet, Vet, Visit services
  • Total 2 supporting services, including Spring Cloud Config and Eureka Service discovery
  • Full supports of ECS cluster, ASG, ALB/Target Group, Route53,etc.

Prerequisite:

We have tested and completed the whole labs in Amazon Linux, binding with the right instance role for managed AWS resources:

准备好 AWS 环境

• 在 AWS 上通过给EC2 Instance 绑定合适的 IAM 角色（推荐）

• 还需要准备一个 Keypair （密钥对）用来绑定到新启动的 EC2 实例上，进行后续的登陆和操作

Lab tools:

• Terraform version 0.9+
• Docker version 17.03.1-ce, build 7392c3b/17.03.1-ce
• docker-compose version 1.8.0, build f3628c7
• git version 2.7.5
• python 3.x for running boto3 scripts
• maven & java 1.8 runtime to build java projects

Preparing Terraform runtime:

1. Download Terraform 0.9+
2. For Linux system,

wget https://releases.hashicorp.com/terraform/0.14.10/terraform_0.14.10_linux_amd64.zip
unzip terraform_*.zip
sudo mv terraform /usr/local/bin/
sudo chmod +x /usr/local/bin/terraform
terraform --version

3. Varify Terraform 环境

Prepare Docker & Docker Compose runtime：

Refer AWS document for details.

sudo yum install -y docker
sudo service docker start
sudo usermod -a -G docker ec2-user 
#Log out and log back in again to pick up the new docker group permissions.
docker info

sudo curl -L https://github.com/docker/compose/releases/download/1.10.0/docker-compose-`uname -s`-`uname -m` > docker-compose 
sudo mv docker-compose /usr/local/bin/
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
docker-compose version 1.10.0, build 4bd6f1a

准备好 git 的环境：

sudo yum install -y git

Preparing python3.4 runtime： Please refer How do I create an isolated Python 3.4 environment with Boto 3 on Amazon EC2 using virtualenv? for details:

sudo yum install python34
which python3.4
cd /home/ec2-user
mkdir venv
cd venv
virtualenv -p /usr/bin/python3.4 python34
source /home/ec2-user/venv/python34/bin/activate
which python
pip install boto3

# Add the result to the .bashrc file

vim ~/.bashrc

source /home/ec2-user/venv/python34/bin/activate

Preparing Maven & java 1.8 runtime：

sudo yum install -y java-1.8.0-openjdk-devel
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-2.b11.30.amzn1.x86_64/jre/

# Add the JAVA_HOME to the .bashrc file to make it effect next time you logout/login
vim ~/.bashrc
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-2.b11.30.amzn1.x86_64/jre/

sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven
mvn --version
