Issue: #458

  1. Provision of cloud resources (virtual machine + disk) to a popular cloud providers for PostgreSQL cluster deployment:

    • AWS
    • GCP
    • Azure
    • DigitalOcean
    • Hetzner Cloud

  2. Create a Cloud Load Balancer - entry point for connecting to a database in a cluster (if 'cloud_load_balancer' is 'true', default: true)

    • AWS Elastic Load Balancer (ELB) - external and internal
    • GCP Proxy Network Load Balancer - external only (TODO: internal)
    • Azure Load Balancer - external and internal
    • DigitalOcean Load Balancer - external and internal
    • Hetzner Cloud Load Balancer - external and internal

  3. Create a Bucket in the cloud and configure backups to this bucket (if 'pgbackrest_install' or 'wal_g_instal' is 'true'). Enabled by default (pgbackrest) for AWS, GCP, and Azure. Add the pgbackrest_auto_conf=false variable if you want to manage the backup configuration yourself.

    • AWS S3 Bucket
    • GCP Bucket
    • Azure Blob Storage
    • DigitalOcean Spaces
    • Hetzner Cloud (TODO: currently, Hetzner Cloud does not provide S3 storage)

Role: cloud-resources

Examples:

AWS

export AWS_ACCESS_KEY_ID=********
export AWS_SECRET_ACCESS_KEY=********

ansible-playbook deploy_pgcluster.yml \
  --user=ubuntu --extra-vars \
    "cloud_provider=aws \
     cloud_load_balancer=true \
     server_count=3 \
     server_location=us-east-2 \
     server_type=m5.xlarge \
     server_image=ami-05fb0b8c1424f266b \
     volume_size=100 \
     ssh_public_keys=\"$(cat $HOME/.ssh/id_rsa.pub)\""

Note: "ami-05fb0b8c1424f266b" is Ubuntu 22.04 LTS (from 2023-12-07)

GCP

export GCP_SERVICE_ACCOUNT_CONTENTS='{
  ********
}'

ansible-playbook deploy_pgcluster.yml \
  --user=root --private-key=$HOME/.ssh/id_rsa --extra-vars \
    "cloud_provider='gcp' \
     cloud_load_balancer=true \
     server_count=3 \
     server_location='us-central1' \
     server_type='n2-standard-4' \
     server_image='projects/ubuntu-os-cloud/global/images/family/ubuntu-2204-lts' \
     volume_size=100 \
     ssh_public_keys=\"$(cat $HOME/.ssh/id_rsa.pub)\""

Azure

export AZURE_SUBSCRIPTION_ID=********
export AZURE_CLIENT_ID=********
export AZURE_SECRET=********
export AZURE_TENANT=********

ansible-playbook deploy_pgcluster.yml \
  --user=azureadmin --private-key=$HOME/.ssh/id_rsa --extra-vars \
    "cloud_provider='azure' \
     server_count=3 \
     server_location='eastus' \
     server_type='Standard_D2s_v3' \
     volume_size=100 \
     ssh_public_keys=\"$(cat $HOME/.ssh/id_rsa.pub)\""

Note: instead of 'server_image', use variables: azure_vm_image_offer, azure_vm_image_publisher, azure_vm_image_sku, azure_vm_image_version. Default: '0001-com-ubuntu-server-jammy', 'Canonical', '22_04-lts-gen2', 'latest'.

DigitalOcean

export DO_API_TOKEN=********

ansible-playbook deploy_pgcluster.yml \
  --user=root --extra-vars \
    "cloud_provider='digitalocean' \
     cloud_load_balancer=true \
     server_count=3 \
     server_location='nyc1' \
     server_type='g-4vcpu-16gb' \
     server_image='ubuntu-22-04-x64' \
     volume_size=100 \
     ssh_public_keys=\"$(cat $HOME/.ssh/id_rsa.pub)\""

Hetzner Cloud

export HCLOUD_API_TOKEN=********

ansible-playbook deploy_pgcluster.yml \
  --user=root --extra-vars \
    "cloud_provider='hetzner' \
     cloud_load_balancer=true \
     server_count=3 \

     server_image='ubuntu-22.04' \
     volume_size=100 \
     ssh_public_keys=\"$(cat $HOME/.ssh/id_rsa.pub)\""

Additionally:

  • Docker image 'vitabaks/postgresql_cluster'
    • includes repository code, ansible, and all necessary dependencies.
  • New roles:
    • authorized-keys
      • These SSH public keys will be added to the server's ~/.ssh/authorized_keys file.
      • variable: ssh_public_keys (optional, default '')
    • mount
      • Configure mount points in /etc/fstab and mount the file system
      • variables:
        • mount (optional, default '')
        • pg_data_mount_path (default '/pgdata')
        • pg_data_mount_fstype (default 'ext4')
      • an empty disk will be automatically detected for cloud providers
      • ZFS pool will be created if 'zfs' specified in the mount.fstype variable.
  • Automatically generate passwords for patroni_superuser_password, patroni_replication_password, patroni_restapi_password, pgbouncer_auth_password (if not defined)
    • and print superuser password in “connection info” after deployment
    • if the variable 'mask_password' is 'true' (default 'false'), do not print the superuser password in connection info
  • install perf, FlameGraph and postgres dbgsym/debuginfo packages
    • variable install_perf, default 'false'
  • Extension Auto-Setup
    • This feature simplifies the integration and configuration process for PostgreSQL third-party extensions. This automated approach eliminates the need for manual configuration, allowing users to seamlessly integrate PostgreSQL extensions. To activate the "Extension Auto-Setup", specify the enable_<extension_name>=true variable.
    • List of extensions: timescaledb, citus, pg_repack, pg_cron, pgaudit, pgvector, postgis, pgrouting, pg_stat_kcache, pg_wait_sampling, pg_partman
  • Add the ability to execute pre and post-deploy command
    • Variables: pre_deploy_command, post_deploy_command
    • This can be a direct command, a bash script content, or a path to a script on the host.

Note: Azure load balancer doesn’t support the scenario of accessing the frontend of internal load balancer from the participating backend pool virtual machine. Please refer this document for detailed information.
This way, you can successfully connect to the database using the IP address of the load balancer from any other virtual machines, but not from the database server itself.
