Glances是一个由python开发的跨平台系统资源监控程序，支持web查看、系统数据API调用等功能。
官网地址：https://nicolargo.github.io/glances
Github地址：https://github.com/nicolargo/glances
文档地址：https://glances.readthedocs.io/en/latest
Docker Hub：https://hub.docker.com/r/nicolargo/glances
1. 安装准备
系统：ubuntu 20.4
工具：docker和docker-compose
2. 搭建
Docer控制台运行效果。
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host --network host -it nicolargo/glances:latest-full
下面通过docker-compose搭建，实现web和API调用。
2.1. 创建数据存放位置
mkdir -p /data/docker_data/glances ## 创建文件夹
cd /data/docker_data/glances ## 进入文件夹
vim docker-compose.yml ## 创建docker-compose
2.2. 编辑docker-compose.yml
version: '3'
services:
glances:
image: nicolargo/glances:latest-full
container_name: glances
restart: always
ports:
- 61208-61209:61208-61209
pid: host
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
- "GLANCES_OPT=-w"
networks:
- mynet
networks: # 连接外部网络，方便内部代理
mynet:
external: true
2.3. 新建docker网络
已经创建的略过。
# 创建一个公用的docker网络
docker network create mynet
# 查看docker网络情况
docker network ls
# 显示如下信息
NETWORK ID NAME DRIVER SCOPE
0134ad30defd bridge bridge local
29474e75ede0 host host local
33bc01a2e0d0 mynet bridge local # 刚刚新建的网络
2.4. 拉去镜像开始安装
docker-compose up -d
3. 使用及展示
打开浏览器访问：http://ip:61208
4. 设置用户密码访问
删除已创建的glances容器。
root@ubuntu:/data/docker_data/glances# docker-compose down
4.1. 创建密码存放位置
## 创建密码文件存放位置
root@ubuntu:/data/docker_data/glances# mkdir -p /data/docker_data/glances/secrets
root@ubuntu:/data/docker_data/glances# vim docker-compose.yml
4.2. 编辑docker-compose.yml
version: '3'
services:
glances:
image: nicolargo/glances:latest-full
container_name: glances
restart: always
ports:
- 61208-61209:61208-61209
pid: host
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
- "GLANCES_OPT=-w --password"
secrets:
- source: glances_password
target: /root/.config/glances/glances.pwd
networks:
- mynet
secrets:
glances_password:
file: ./secrets/glances_password
networks: # 连接外部网络，方便内部代理
mynet:
external: true
4.3. 获取密码文件
## 运行glances项目
root@ubuntu:/data/docker_data/glances# docker run -d -e GLANCES_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro --name="glances" --pid host -it nicolargo/glances:latest-full
1b1e167607920b39da3f926cb9bb3c4ca5106a85bd1faa2d8077a6dec8863908
## 进入容器内部
root@ubuntu:/data/docker_data/glances# docker exec -it glances sh
## 设置密码，默认用户名为glances，可以通过--username修改（后续设置复杂不推荐）
/glances # glances -s --password
## 输入两次密码，并保存
Define the Glances server password (glances username):
Password (confirm):
Do you want to save the password? [Yes/No]: yes
Glances XML-RPC server is running on 0.0.0.0:61209
Announce the Glances server on the LAN (using 172.17.0.2 IP address)

4.5. 登录效果
5. API调用
详细的调用方式查看文档：API (Restfull/JSON) documentation — Glances 3.3.0.1 documentation
root@ubuntu:~# curl http://glances:testglances@192.168.100.111:61208/api/3/diskio
[{"time_since_update": 2.9525327682495117, "disk_name": "sr0", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}, {"time_since_update": 2.9525327682495117, "disk_name": "sda", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}, {"time_since_update": 2.9525327682495117, "disk_name": "sda1", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}, {"time_since_update": 2.9525327682495117, "disk_name": "sda2", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}, {"time_since_update": 2.9525327682495117, "disk_name": "sda3", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}, {"time_since_update": 2.9525327682495117, "disk_name": "dm-0", "read_count": 0, "write_count": 0, "read_bytes": 0, "write_bytes": 0, "key": "disk_name"}]
root@ubuntu:~#
6. 关闭web访问
如果仅需要API调用，通过修改docker-compose.yml关闭web访问。
environment:
- "GLANCES_OPT=-w --password --disable-webui"
