在Docker中使用Zabbix 进行监控

Container

容器提供了以下* Zabbix服务*,请参阅[ Zabbix文件](http://www.zabbix.com/)附加信息。

  • Zabbix Server 端口号10051.
  • Zabbix Java Gateway 端口号 10052.
  • Zabbix Web UI 端口号 80 (例子 http://$container_ip/zabbix )
  • Zabbix Agent.
  • MySQL实例支持 Zabbix, 用户名密码都是 zabbix.
  • Monit管理在这里 (http://$container_ip:2812, user 'myuser' and password 'mypassword').

如何使用

你可以执行以下命令运行Zabbix服务.

docker run -d -P --name zabbix  berngp/docker-zabbix

上面的命令要求在dockerberngp/docker-zabbix镜像的时候开放所有** Zabbix **指定所有本地端口去运行实例。 运行 docker ps -f name=zabbix 检查端口映射到容器的'80'端口, Zabbix Web UI.

打开 http://<docker实例的ip地址>:<docker指定的端口默认是80>/zabbix

一个将端口80映射到49184端口的例子。

$ docker ps -f name=zabbix
CONTAINER ID        IMAGE                         COMMAND                CREATED             STATUS              PORTS                                                                                                NAMES
970eb1571545        berngp/docker-zabbix:latest   "/bin/bash /start.sh   18 hours ago        Up 2 hours          0.0.0.0:49181->10051/tcp, 0.0.0.0:49182->10052/tcp, 0.0.0.0:49183->2812/tcp, 0.0.0.0:49184->80/tcp   zabbix

如果你想在Docker主机绑定容器特定的端口,你可以执行以下命令:

docker run -d \
           -p 10051:10051 \
           -p 10052:10052 \
           -p 80:80       \
           -p 2812:2812   \
           --name zabbix  \
           berngp/docker-zabbix

上面的命令会* Zabbix服务通过 10051 端口启动,而Web界面则通过 80 *端口运行名字是Zabbix的实例。 要有耐心的花一两分钟配置MySQL实例启动服务。你可以使用docker logs -f $contaienr_id记录日志。

以上都做完了Zabbix Web UI 就已经运行了 你可以通过http://$container_ip/zabbix访问. 用户名是 admin密码是 zabbix.

Apparmor 细节 (仅仅在Debian和Ubuntu)

如果你想容器使用Monit控制和监视各个进程, 你需要配置Docker的默认Apparmor配置文件. 目前,唯一的办法就是添加trace能力和运行的容器通过AppArmor,使用下面的标识RUN command:

--cap-add SYS_PTRACE  --security-opt apparmor:unconfined

如果添加vast号日志信息写入你得你的系统日志,并每10秒跟踪一次进程!

挖掘Docker Zabbix 容器

如果你想查看部署运行容器的内容, 你可以通过如下命令 bash shell through docker's exec . 执行以下命令.

docker exec -i -t zabbix /bin/bash

开发者

我建议你通过发行版建立Docker, 如果你使用的是 Mac OSX 我建议你利用 boot2docker, 你也可以使用Vagrantfile 创建一个_Docker_环境.

用Vagrantfile文件设置你得Docker环境

运行其中包含的 Vagrantfile 文件你需要安装VirtualBoxVagrant . 实际中我使用了_VirtualBox_ 4.3.6 和_Vagrant_ 1.4.1.使用_Vagrantfile_ 构建一个最小化的_Ubuntu 64_ 操作系统_VirtualBox Guest Additions_ along with Docker and its dependencies. 第一次你需要执行vagrant up 完成安装和构建, 然后你执行 vagrant reload去完成vagrant的重启.在完成这一切以后你只需要执行 vagrant ssh去ssh连接你得机器并且用which docker命令找到 Docker 所在位置

Be aware that the Vagrantfile depends on the version of VirtualBox and may run into problems if you don't have the latest versions.

创建Docker Zabbix 仓库.

Within an environment that is already running docker, checkout the docker-zabbix code to a known directory. If you are using the Vagrantfile, as mentioned above, it will be available by default in the /docker/docker-zabbix directory. From there you can execute a build and run the container.

e.g.

# 进入容器构建代码目录.
cd /docker/docker-zabbix
# 构建容器.
docker build -t berngp/docker-zabbix .
#启动他!
docker run -i -t -P --name=zabbix berngp/docker-zabbix

Container

The container provides the following Zabbix Services, please refer to the Zabbix documentation for additional info.

  • A Zabbix Server at port 10051.
  • A Zabbix Java Gateway at port 10052.
  • A Zabbix Web UI at port 80 (e.g. http://$container_ip/zabbix )
  • A Zabbix Agent.
  • A MySQL instance supporting Zabbix, user is zabbix and password is zabbix.
  • A Monit deamon managing the processes (http://$container_ip:2812, user 'myuser' and password 'mypassword').

Usage

You can run Zabbix as a service executing the following command.

docker run -d -P --name zabbix  berngp/docker-zabbix

The command above is requesting docker to run the berngp/docker-zabbix image in the background, publishing all ports to the host interface assigning the name of zabbix to the running instance. Run docker ps -f name=zabbix to review which port was mapped to the container's port '80', the Zabbix Web UI.

Open http://<ip of the host running the docker deamon>:<host port mapped to the container's port 80>/zabbix

In the example bellow the container's port 80 is mapped to 49184.

$ docker ps -f name=zabbix
CONTAINER ID        IMAGE                         COMMAND                CREATED             STATUS              PORTS                                                                                                NAMES
970eb1571545        berngp/docker-zabbix:latest   "/bin/bash /start.sh   18 hours ago        Up 2 hours          0.0.0.0:49181->10051/tcp, 0.0.0.0:49182->10052/tcp, 0.0.0.0:49183->2812/tcp, 0.0.0.0:49184->80/tcp   zabbix

If you want to bind the container's port with specific ports from the host running the docker daemon you can execute the following:

docker run -d \
           -p 10051:10051 \
           -p 10052:10052 \
           -p 80:80       \
           -p 2812:2812   \
           --name zabbix  \
           berngp/docker-zabbix

The above command will expose the Zabbix Server through port 10051 and the Web UI through port 80 on the host instance, among others and associate it with the name zabbix. Be patient, it takes a minute or two to configure the MySQL instance and start the proper services. You can tail the logs using docker logs -f $contaienr_id.

After the container is ready the Zabbix Web UI should be available at http://$container_ip/zabbix. User is admin and password is zabbix.

Apparmor Specifics (Debian and Ubuntu)

The container uses Monit for controlling and observing the individual processes, which requires capabilities denied by Docker's default Apparmor profile. Currently, the only workaround is to add the trace capability and running the container without being fenced by Apparmor, using following flags in the RUN command:

--cap-add SYS_PTRACE  --security-opt apparmor:unconfined

Not doing so will result in a vast number of log messages polluting your syslog, as Monit tries to trace the processes all 10 seconds!

Exploring the Docker Zabbix Container

Sometimes you might just want to review how things are deployed inside a running container, you can do this by executing a bash shell through docker's exec command. Execute the command bellow to do it.

docker exec -i -t zabbix /bin/bash

Developers

I suggest you install docker through your distribution, if using Mac OSX I suggest you leverage boot2docker, as an option the project has a Vagrantfile that you can use to create a virtual instance with Docker.

Setting your Docker environment with the Vagrantfile

To run the included Vagrantfile you will need VirtualBox and Vagrant installed. Currently I am testing it against VirtualBox 4.3.6 and Vagrant 1.4.1. The Vagrantfile uses a minimal Ubuntu Precise 64 box and installs the VirtualBox Guest Additions along with Docker and its dependencies. The first time you execute a vagrant up it will go through an installation and build process, after its done you will have to execute a vagrant reload. After that you should be able to do a vagrant ssh and find that Docker is available using a which docker command.

Be aware that the Vagrantfile depends on the version of VirtualBox and may run into problems if you don't have the latest versions.

Building the Docker Zabbix Repository.

Within an environment that is already running docker, checkout the docker-zabbix code to a known directory. If you are using the Vagrantfile, as mentioned above, it will be available by default in the /docker/docker-zabbix directory. From there you can execute a build and run the container.

e.g.

# CD into the docker container code.
cd /docker/docker-zabbix
# Build the contaienr code.
docker build -t berngp/docker-zabbix .
# Run it!
docker run -i -t -P --name=zabbix berngp/docker-zabbix
