持续部署工具CDS上手

一、CDS简介

CDS是Go语言开发的企业级持续部署工具和开源的DevOps自动化平台，支持的特性非常的多 CDS部署方式有多种，docker-compose方式，helm安装到kubernetes，二进制安装。这里主要介绍二进制安装方式。 更多关于CDS的知识，可以访问官网CDS

Github仓库地址：https://github.com/ovh/cds

要求: redis postgresql 9.5+

二、安装依赖

1.安装redis

安装redis

1yum -y install epel-release
2yum -y install redis

运行redis

1systemctl enable --now redis

2.安装postgres

1.添加postgres源，CentOS7自带的postgres版本为9.2不满足要求

1yum -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

2.安装postgres96

1yum -y install postgresql96-server postgresql96

3.初始化postgres并运行

1/usr/pgsql-9.6/bin/postgresql96-setup initdb
2sed -i '/TYPE/ahost    all             all             0.0.0.0/0               md5' /var/lib/pgsql/9.6/data/pg_hba.conf
3sed -i "/#listen_addresses/alisten_addresses ='*'" /var/lib/pgsql/9.6/data/postgresql.conf
4systemctl enable --now postgresql-9.6

4.创建用户以及数据库

缺换到postgres用户

1su - postgres
2psql

创建cds用户和数据库

1create user cds login password 'cds';
2create database cds owner cds;

三、CDS部署

1.下载二进制文件

从github上下载最新版本的cds

 1mkdir $HOME/cds
 2cd cds
 3
 4LAST_RELEASE=$(curl -s https://api.github.com/repos/ovh/cds/releases | grep tag_name | head -n 1 | cut -d '"' -f 4)
 5OS=linux   # linux, darwin, windows, freebsd, openbsd
 6ARCH=amd64 # 386, arm, amd64, arm64, ppc64le
 7
 8# 从GitHub下载二进制文件
 9curl -L https://github.com/ovh/cds/releases/download/$LAST_RELEASE/cds-engine-$OS-$ARCH -o cds-engine
10curl -L https://github.com/ovh/cds/releases/download/$LAST_RELEASE/cdsctl-$OS-$ARCH -o cdsctl
11
12chmod +x cds-engine cdsctl

2.生成配置文件

默认配置文件conf.toml中默认连的redis和数据库都是localhost，数据库默认用户cds，密码cds，数据库名cds，如果不是需要修改配置文件。

1cd $HOME/cds
2./cds-engine config new > conf.toml
3sed -i '/localhost/s@localhost@127.0.0.1@' conf.toml

3.初始化数据库

1cd $HOME/cds
2# 下载sql文件
3./cds-engine download sql --config conf.toml
4# 将sql文件导入到数据库中
5./cds-engine database upgrade --db-host 127.0.0.1 --db-user cds --db-password cds --db-name cds --db-sslmode disable --db-port 5432 --migrate-dir sql

4.运行cds api

1cd $HOME/cds
2# 下载workers
3./cds-engine download workers --config conf.toml
4# 运行api
5./cds-engine start api --config conf.toml

检查服务运行是否正常

1curl http://localhost:8081/mon/version
2{"version":"0.44.0+cds.12344","architecture":"amd64","os":"linux","git_hash":"da180756ef91a2a7b87b3501bc893c6a5e0f8ee1","build_time":"02/06/20-16:24:06","db_migrate":"181"}
3
4curl http://localhost:8081/mon/status
5{"now":"0001-01-01T00:00:00Z","lines":[{"status":"OK","component":"Global/Maintenance","value":"false","type":""},{"status":"AL","component":"Global/Status","value":"3 services","type":""},{"status":"OK","component":"Global/Version","value":"0.44.0+cds.12344","type":""},{"status":"AL","component":"Global/api","value":"2","type":""},{"status":"OK","component":"Global/dbmigrate","value":"0","type":""},{"status":"OK","component":"Global/doc","value":"1","type":""},{"status":"OK","component":"Global/elasticsearch","value":"0","type":""},{"status":"OK","component":"Global/hatchery","value":"0","type":""},{"status":"OK","component":"Global/hooks","value":"0","type":""},{"status":"OK","component":"Global/repositories","value":"0","type":""},{"status":"OK","component":"Global/vcs","value":"0","type":""},{"status":"OK","component":"Version","value":"0.44.0+cds.12344","type":""},{"status":"OK","component":"Uptime","value":"2562047h47m16.854775807s","type":""},{"status":"OK","component":"Time","value":"12h6m2s","type":""},{"status":"OK","component":"Hostname","value":"node0","type":""},{"status":"OK","component":"CDSName","value":"api_musandsadhaw","type":""},{"status":"OK","component":"Nb of Panics","value":"0","type":""},{"status":"OK","component":"Event Broker","value":"⚠ ","type":""},{"status":"OK","component":"Object-Store","value":"Filesystem Storage","type":""},{"status":"AL","component":"SMTP Ping","value":"KO: No SMTP configuration","type":""},{"status":"OK","component":"Database Conns","value":"10","type":""},{"status":"OK","component":"Worker Model Errors","value":"0","type":""},{"status":"OK","component":"Nb of CDS Migrations in progress","value":"0","type":""},{"status":"OK","component":"Version","value":"0.44.0+cds.12344","type":""},{"status":"OK","component":"Uptime","value":"2562047h47m16.854775807s","type":""},{"status":"OK","component":"Time","value":"12h8m34s","type":""},{"status":"OK","component":"Hostname","value":"node0","type":""},{"status":"OK","component":"CDSName","value":"api_upbdij","type":""},{"status":"OK","component":"Nb of Panics","value":"0","type":""},{"status":"OK","component":"Event Broker","value":"⚠ ","type":""},{"status":"OK","component":"Object-Store","value":"Filesystem Storage","type":""},{"status":"AL","component":"SMTP Ping","value":"KO: No SMTP configuration","type":""},{"status":"OK","component":"Database Conns","value":"10","type":""},{"status":"OK","component":"Worker Model Errors","value":"0","type":""},{"status":"OK","component":"Nb of CDS Migrations in progress","value":"0","type":""}]}

能够正常返回数据，则说明api服务运行正常。

5.运行cds ui

1cd $HOME/cds
2./cds-engine download ui --config conf.toml
3./cds-engine start ui --config conf.toml
4

创建管理员账户

密码需要符合复杂度要求

1export INIT_TOKEN=`./cds-engine config init-token --config conf.toml`
2./cdsctl signup --api-url http://localhost:8081 --email admin@localhost.local --username admin --fullname admin

网页访问UI，打开浏览器，访问http://localhost:8080

6.运行本地孵化器

1./cds-engine start hatchery:local --config $HOME/cds/conf.toml

7.关于cds

一次运行所有的服务

1./cds-engine start api ui hooks hatchery:local --config conf.toml

强烈推荐单独运行各个服务

 1
 2./cds-engine start api --config conf.toml
 3
 4./cds-engine start ui --config conf.toml
 5
 6./cds-engine start hooks --config conf.toml
 7
 8./cds-engine start vcs --config conf.toml
 9
10./cds-engine start hatchery:local --config conf.toml
11./cds-engine start hatchery:docker --config conf.toml
12./cds-engine start hatchery:swarm --config conf.toml
13./cds-engine start hatchery:marathon --config conf.toml
14./cds-engine start hatchery:openstack --config conf.toml
15./cds-engine start hatchery:vsphere --config conf.toml
