A baseline application to deploy for ONUG projects / proof of concepts

The intent of ONUG is to select a sample application to build and operate in a variety of different contexts. Our two intial contexts are for the working groups

• Monitoring and Analytics (M&A or MA)
• Software Defined Security Service (SDSS)

Acknowledgements of open source code:

We started here at the base WikiMedia dowload libraries, freely dowloadable under GNU General Pulbic License. https://www.mediawiki.org/wiki/Download

Requirements

• Terraform v0.11.8
• Ansible v2.6.4
• AWS-CLI configured with the AWS Credentials.
• The SSH key to be used registered in AWS and in the machine running the scripts, with the same name it has in AWS.

Basic Steps

1. Change the server and AWS variables in scripts/mediawiki_deploy.sh
2. If necessary change the server access variables in scripts/ansible.sh
3. If necessary change the Terraform backend information in /terraform/mediawiki/must-have.tf
4. Make the scripts executables chmod -R +x scripts/
5. Run the command ./scripts/mediawiki_deploy.sh

More information about the deployment can be found at

• ansible/mediawiki/README.md
• terraform/mediawiki/README.md

Detailed Example Steps

• Bring you from the ground-up on a brand-new ubuntu 16.04 server

# update apt-get
sudo apt-get update

# install / upgrade pip
sudo apt-get install python-pip
pip install --upgrade pip

# install awscli
pip install awscli --user

wrgeorge1983@ubuntu-s-2vcpu-4gb-nyc1-01:~$ aws configure --profile apcela
AWS Access Key ID [None]: AKINOTAREALACCESSKEYIDQ
AWS Secret Access Key [None]: NOTAREALSECRETEACCESSKEY
Default region name [None]: us-east-1
Default output format [None]: 

# create s3 bucket to use (if not using an existing one), keep track of the name ('apcela-terraform') in this instance
s3 mb apcela-terraform --profile apcela

# install ansible
pip install ansible

# install terraform
sudo apt-get install unzip

wget https://releases.hashicorp.com/terraform/0.11.8/terraform_0.11.8_linux_amd64.zip
unzip terraform_0.11.8_linux_amd64.zip
sudo mv terraform /usr/local/bin/
terraform --version 

# pull repo
git clone  https://github.com/onug/reference_workload_wikimedia.git

# update configs
cd onug
vi scripts/mediawiki_deploy.sh
    export TF_VAR_aws_profile="apcela" # profile name from configuring AWS CLI
    edit aws_region_alias to use1 # us-east-1

vi terraform/mediawiki/must-have.tf
    edit terraform.backend "s3".bucket # to bucket created earlier
    edit terraform.backend "s3".profile # to aws cli profile created earlier


# execute
./scripts/mediawiki_deploy.sh

# destroy (Important! Especially if you don't intend to keep paying for this)
./scripts/mediawiki_destroy.sh
