docker启动postgres

Copy
docker run -d
–name sonar-postgres
-e POSTGRES_PASSWORD=postgres
-e PGDATA=/var/lib/postgresql/data/pgdata
-v /custom/mount:/var/lib/postgresql/data
postgres
安装客户端psql，通过yum安装postgresql-server会附带安装psql。也可以安装pgAdmin。

Copy
yum install postgresql-server
连接到服务器

Copy
psql -h localhost -U postgres -W
创建数据库

Copy
postgres=# CREATE DATABASE sonarqube WITH OWNER=postgres ENCODING=‘UTF8’ CONNECTION LIMIT=-1;
CREATE DATABASE

docker启动sonarqube#
先创建几个volume用于存储数据

Copy
docker volume create sonarqube_data
docker volume create sonarqube_extensions
docker volume create sonarqube_logs
更改一些系统参数

Copy
sysctl -w vm.max_map_count=262144
sysctl -w fs.file-max=65536
ulimit -n 65536
ulimit -u 4096
如果不设置可能会出现错误：vm.max_map_count 65530 is too low

Copy

启动sonarqube

Copy
docker run -d --name sonarqube
-p 9000:9000
–link sonar-postgres
-e SONAR_JDBC_URL=jdbc:postgresql://sonar-postgres/sonarqube
-e SONAR_JDBC_USERNAME=postgres
-e SONAR_JDBC_PASSWORD=postgres
-v sonarqube_data:/opt/sonarqube/data
-v sonarqube_extensions:/opt/sonarqube/extensions
-v sonarqube_logs:/opt/sonarqube/logs
sonarqube:8.3.1-community
本来是要使用8.4的，但是是因为有个BUG就放弃了。该BUG会在8.4.1修改。

创建项目#
访问服务地址http://localhost:9000/，然后登录界面，用户名admin，密码admin登录。

安装中文包

创建项目

创建令牌

使用golangci-lint分析代码#
golangci-lint聚合了很多工具，下面只是作为演示，具体请查看官网。
在项目根目录下新建文件.golangci.yml。具体示例可查看https://github.com/golangci/golangci-lint/blob/master/.http://www.jconline.org/.yml

Copy

example link : https://github.com/golangci/golangci-lint/blob/master/.golangci.example.yml

run:
timeout: 1m
skip-dirs-use-default: true

linters-settings:
dupl:
# tokens count to trigger issue, 150 by default
threshold: 100

linters:
enable:
- dupl
- golint
使用docker镜像生成xml格式的分析文件，出处请见

Copy
$ mkdir sonar

sonar客户端扫描#
在项目根目录新建一个名为sonar-project.properties的文件

Copy
