Getting Started

edb-pot tool is an easy way to provision Cloud resources and deploy PostgreSQL, EDB Postgres Advanced Server and tools (high availability and monitoring) for Proof Of Technology.

Supported Cloud providers are AWS, Azure and Google Cloud.

edb-pot helps user to deploy custom Postgres Reference Architectures tailored for showing functionalities of EDB Tech.

edb-pot is an open source tool and is not officially supported by EDB Support. It is maintained and supported by the GitHub members of this repository. Please provide feedback by posting issues and providing pull requests.

Before starting to delve into this repository, it is best to get familiar with the steps in the deployment process of a specific cloud (AWS, Azure and Google Cloud).

Pre-Requisites

edb-pot is dependent on following components. Install the following components before using it.

1. Python 3
2. pip3

Third party pre-requisites:

1. Latest vendor Cloud CLI or SDK ( AWS, Azure or Google Cloud )

   Depending on the cloud provider, install the latest version for: AWS CLI, Azure CLI or Google Cloud SDK on the system.

2. Terraform >= 0.13

3. Ansible >= 2.9

To help the installation of the third party pre-requisites listed above, edb-pot provides installation scripts for Linux (x64) and MacOS (x64). Please refer to section Pre-Requisites installation scripts.

Installation

From source code

Installation is done using the pip3 command. Once the code has been downloaded, either by cloning the repository or downloading a release, go to the created folder and run the command pip3 install:

$ cd postgres-deployment
$ sudo pip3 install . --upgrade

From Pypi

$ sudo pip3 install edb-pot

Make sure the tool is well installed by running the command:

$ edb-pot --version

Shell auto-completion

edb-pot supports command line auto-completion with the tab key.

Supported shells are bash ans zsh.

To enable auto-completion in current session, the following command must be ran:

$ eval "$(register-python-argcomplete edb-pot)"

To enable auto-completion for all the sessions, the command above must be added at the end of your ~/.bashrc file or ~/.zshrc file, depending on the shell you use.

Pre-Requisites installation scripts

To ease installation of the third party pre-requisites tools like aws, terraform, ansible, etc.. some bash installation scripts are provided for Linux (x64) and MacOS (x64). They are located in the script/ folder.

The following packages are required in order to execute the installation script: gcc (Linux only), python3-devel (Linux only), unzip, wget, tar. These packages should be installed through usual package manager (dnf, apt, brew, etc..).

Finally, Python virtualenv must be installed with root privileges:

$ sudo pip3 install virtualenv

The pre-requisites installation script can now be run. By default, third party tools are installed into the folder $HOME/.edb-cloud-tools, this path can be changed by setting the environment variable INSTALL_PATH.

On Linux:

$ /usr/local/share/edb-pot/scripts/install_requirements_linux_x64.sh

On MacOS (Python 3.9 installed with brew):

$ /usr/local/share/edb-pot/scripts/install_requirements_darwin_x64.sh

The last action is to add the installation path to the PATH variable. If your shell is bash, just enter:

$ source ~/.bashrc

For other shells, you have to re-export the environment variable PATH this way:

$ export PATH=$PATH:$HOME/.edb-cloud-tools/bin

You can now check if the tools are ready to use with the commands aws --version, ansible --version, etc..

Usage

Each new deployment will be done under a dedicated name space, this the <PROJECT_NAME>.

edb-pot CLI features are implemented through sub-commands. Each sub-command can be executed like this:

$ edb-pot <CLOUD_VENDOR> <SUB_COMMAND> [<PROJECT_NAME>]

Cloud vendor list

• aws: Amazon Web Services
• azure: Microsoft Azure Cloud
• gcloud: Google Cloud

Sub-commands

• configure: New project initialization and configuration
• provision: Cloud resources provisioning
• destroy: Cloud resources destruction
• deploy: Postgres and tools deployment
• display: Display the project information
• passwords: Display the project passwords
• show: Show configuration
• list: List projects
• specs: Show Cloud Vendor default specifications
• logs: Show project logs
• remove: Remove project

How to Use

Deployment of new project should follow the work flow below:

1. Configure Cloud credentials
2. Project configuration
3. Cloud resources provisioning
4. Postgres and tools deployment

Configure Cloud credentials

This step depends on the target Cloud vendor.

AWS credentials configuration

AWS credentials configuration will be done through aws tool. For this step, we need to get your AWS Access Key ID and AWS Secret Access Key. For more information about Amazon Access Key management, please go to official documentation page.

Run the following command and enter the Access Key ID and Secret Access Key:

$ aws configure

Azure credentials configuration

Azure Cloud credentials configuration can be achieved using the az tool with the following command:

$ az login --use-device-code

GCloud credentials configuration

GCloud credentials configuration includes more steps than the other Cloud vendors. GCloud project ID is required.

1. Login with your email address:

$ gcloud auth login <LOGIN_EMAIL> --no-launch-browser

2. Open the link in your browser and copy the given verification code.
3. Project configuration

$ gcloud config set project <PROJECT_ID>

4. To find the IAM account of the service, please enter the following command to list service accounts:

$ gcloud iam service-accounts list

5. Finally, to create and download a new service account key:

$ gcloud iam service-accounts keys create ~/accounts.json --iam-account=<IAM_ACCOUNT>

The JSON file $HOME/accounts.json must be kept and will be required by edb-pot.

Project configuration

Once Cloud vendor credentials have been configured, you can proceed with project configuration step.

Cloud vendor specifications

edb-pot brings default configuration values for the Cloud resources to be provisioned, like instance type, disk size, OS image, additional volumes, etc..

To change these configuration values, you need first to dump the default values with:

$ edb-pot <CLOUD_VENDOR> specs > my_configuration.json

Then, you can edit and update resources configuration stored in the JSON file.

Project initialization

Project initialialization will done using the configure sub-command:

$ edb-deploy <CLOUD_VENDOR> configure <PROJECT_NAME> \
  --route53-access-key <route53-acccess-key> \
  --route53-secret <route53-secret> \
  --email-id <email-id> \
  -u "<EDB_REPO_USERNAME>:<EDB_REPO_PASSWORD>" \
  -r <CLOUD_REGION> \
  -s my_configuration.json

Notes:

• "EDB_REPO_USERNAME:EDB_REPO_PASSWORD"

  EDB Packages repository credentials. Required.

• CLOUD_REGION

  Cloud vendor region. Default value depends on Cloud vendor.

For more details, please use:

$ edb-pot <CLOUD_VENDOR> configure --help

Cloud resources provisioning

After project configuration, we can proceed to Cloud resources provisioning:

$ edb-pot <CLOUD_VENDOR> provision <PROJECT_NAME>

Components deployment

Finally, we can deploy the components with the deploy sub-command:

$ edb-pot <CLOUD_VENDOR> deploy <PROJECT_NAME>

Other features

List of projects:

$ edb-pot <CLOUD_VENDOR> list

Display of projects inventory:

$ edb-pot <CLOUD_VENDOR> display <PROJECT_NAME>

Display of projects passwords:

$ edb-pot <CLOUD_VENDOR> passwords <PROJECT_NAME>

Cloud resources destruction:

$ edb-pot <CLOUD_VENDOR> destroy <PROJECT_NAME>

Project tree deletion:

$ edb-pot <CLOUD_VENDOR> remove <PROJECT_NAME>
