deployment-tool

This repository contains a command tool hdt, which can be used to set up a HStreamDB Cluster with docker.

Quick start

Check environment

• Start HStreamDB requires an operating system kernel version greater than at least Linux 4.14. Check with command:

  uname -r

• Make sure docker is installed.

• Make sure that the log-in user has sudo execute privileges，and configure sudo without password.

• For nodes which deploy HStore instances, mount the data disk to /mnt/data*/.

  • "*" Matching incremental numbers, start from zero
  • one disk should mount to one directory. e.g. if we have two data disks /dev/vdb and /dev/vdc, then /dev/vdb should mount to /mnt/data0 and /dev/vdc should mount to /mnt/data1

Installation

Binaries are available here: https://github.com/hstreamdb/deployment-tool/releases

Generate configuration template && init local environment

./hdt init

The current directory structure will be as follows after running the init command:

├── hdt
└── template                 
    ├── config.yaml
    ├── grafana
    │   ├── dashboards
    │   └── datasources
    ├── prometheus
    └── script

Update config.yaml

Update the config.yaml file with cluster-related information. The configuration in the config.yaml template will deploy a cluster on 3 nodes, each consisting of a HServer instance, a HStore instance, a Meta-Store instance and associated monitoring components. Prometheus 、Grafana and other monitor components will be deploy on a separate node.

To use this configuration file, just update the host information of the node and the ssh key-pair path. The final configuration file may looks like:

global:
  user: "root"
  key_path: "~/.ssh/hstream.pem"
  ssh_port: 22

monitor:
  node_exporter_port: 9100
  cadvisor_port: 7000
  grafana_disable_login: true

hserver:
  - host: 172.24.47.173
  - host: 172.24.47.174
  - host: 172.24.47.175

  - host: 172.24.47.173
    enable_admin: true
  - host: 172.24.47.174
  - host: 172.24.47.175

  - host: 172.24.47.173
  - host: 172.24.47.174
  - host: 172.24.47.175

prometheus:
  - host: 172.24.47.172

grafana:
  - host: 172.24.47.172
