课堂作业 一
使用docker搭建一个可以访问的jenkins服务
使用docker搭建一个可以访问的testlink服务
使用container模式搭建前端和后端服务
普罗米修斯的配置文件
启动node_exporter ：nohup ./node_exporter/node_exporter >> node_exporter.log 2>&1 &
global:
scrape_interval: 15s
evaluation_interval: 15s
scrape_configs:
- job_name: 'prometheus'
static_configs:
- targets: ['localhost:9090']
- job_name: 'node_exporter'
static_configs:
- targets: ['docker.testing-studio.com:9100']
- job_name: 'mysql'
static_configs:
- targets: ['docker.testing-studio.com:9104']
docker run --name prometheus -d -p 9090:9090 -v pwd/prometheus.yml:/etc/prometheus/prometheus.yml -v pwd/rules/:/etc/prometheus/ prom/prometheus
cpu使用率:100 - (avg by (instance) (irate(node_cpu_seconds_total{mode=“idle”}[1m])) * 100)
内存使用率：100*(node_memory_MemTotal_bytes - node_memory_MemFree_bytes - node_memory_Buffers_bytes - node_memory_Cached_bytes) / node_memory_MemTotal_bytes
磁盘使用：100.0 - 100 * ((node_filesystem_avail_bytes{mountpoint=~“/”, device!=“rootfs”} / 1000 / 1000 ) / (node_filesystem_size_bytes{mountpoint=~“/”, device!=“rootfs”} / 1024 / 1024))
启动grafana
docker run --name grafana -d -p 8011:3000 grafana/grafana

使用普罗米修斯+grafana监控mysql
docker run -d --name mysql-exporter -p 9104:9104 -e DATA_SOURCE_NAME=“root:1qaz9ol.@(docker.testing-studio.com :8888)/mysql” prom/mysqld-exporter

docker 搭建分布式UI自动化框架
docker run --name=hub -p 5001:4444 -e GRID_TIMEOUT=0 -e GRID_THROW_ON_CAPABILITY_NOT_PRESENT=true -e GRID_NEW_SESSION_WAIT_TIMEOUT=-1 -e GRID_BROWSER_TIMEOUT=15000 -e GRID_TIMEOUT=30000 -e GRID_CLEAN_UP_CYCLE=30000 -d selenium/hub:3.7.1-beryllium
docker run --name=chrome -p 5902:5900 -e NODE_MAX_INSTANCES=6 -e NODE_MAX_SESSION=6 -e NODE_REGISTER_CYCLE=5000 -e DBUS_SESSION_BUS_ADDRESS=/dev/null -v /dev/shm:/dev/shm --link hub -d selenium/node-chrome-debug:3.7.1-beryllium

课堂作业二
不使用–link 搭建docker grid框架
在学习了jenkins课程之后，搭建起全套的CI流程。
