How to Install Cabot Monitoring Tool using Docker on CentOS 7
To Install Cabot Monitoring Tool using Docker on CentOS 7
Cabot is an open-source, self-hosted monitoring platform written in Python and it provides a web interface that allows you to monitor services and send telephone, SMS or hipchat/email alerts to your support in case of any service failures. It is so simple to install Cabot Monitoring tool using Docker on CentOS 7 machine, and this tutorial covers the ground on the same process.
Installing Cabot Monitoring Tool
First, make sure you install Docker/Docker compose which is very vital for this process. You can install docker by running this command.
[root@linuxhelp ~]# yum install docker
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
.
.
Complete!
Once it is done, you need to start the Docker service.
[root@linuxhelp ~]# systemctl start docker
And then, once it is done, you need to check the status of Docker with the help of the following command.
[root@linuxhelp ~]# systemctl status docker ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service disabled vendor preset: disabled) Active: active (running) since Thu 2018-02-08 11:24:47 IST 5s ago . . o msg=" API listen on /var/run...r.sock" Hint: Some lines were ellipsized, use -l to show in full.
Once it is done, you need to enable the Docker service by running the following command.
[root@linuxhelp ~]# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
Docker-compose is a command line tool to define and configure multi-container docker applications. You can install it with the help of the following command.
[root@linuxhelp ~]# yum install epel-release.noarch -y
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
.
Installed:
epel-release.noarch 0:7-9
Complete!
Install Python as well.
[root@linuxhelp ~]# yum install python-pip &ndash y
Loaded plugins: fastestmirror, langpacks
epel/x86_64/metalink
.
Installed:
python2-pip.noarch 0:8.1.2-5.el7
Complete!
And now type the pip command to install the docker compose.
[root@linuxhelp ~]# pip install docker-compose
Collecting docker-compose
Downloading docker_compose-1.19.0-py2.py3-none-any.whl (115kB)
.
-0.6.2 enum34-1.1.6 functools32-3.2.3.post2 idna-2.6 ipaddress-1.0.19 jsonschema-2.6.0 requests-2.18.4 texttable-0.9.1 urllib3-1.22 websocket-client-0.46.0
You should also install Git packages from their repositories by just running this command.
[root@linuxhelp ~]# yum install git
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
.
.
Complete!
Deploying Cabot container using Docker-compose tool
Now, let us deploy our Cabot docker container with docker-compose command, first we need to have a directory with that name which includes the docker compose file namely docker-compose.yml
[root@linuxhelp ~]# git clone https://github.com/arachnys/cabot.git
Cloning into ' cabot' ...
.
Resolving deltas: 100% (2696/2696), done.
This will create our Cabot folder with all required files to create our container.
Now we can move to our Cabot folder created and add your keys for external services to the configuration files.
[root@linuxhelp cabot]# cp conf/production.env.example conf/production.env
[root@linuxhelp cabot]# cp conf/development.env.example conf/development.env
And finally, you can run the docker-compose command to build your container.
[root@linuxhelp cabot]# docker-compose up -d
Creating network " cabot_default" with the default driver
Creating volume " cabot_datavolume" with default driver
.
.
Creating cabot_redis_1 ...
Creating cabot_web_1 ... done
Creating cabot_beat_1 ... done
Creating cabot_worker_1 ... done
Once, it' s done make sure you' ve Cabot container and its services are up and running.
[root@linuxhelp cabot]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c12731fb7cd3 cabot:web " ./docker-entrypoint." 16 minutes ago Up 16 minutes cabot_worker_1
b9d56548c4f2 cabot:web " ./docker-entrypoint." 16 minutes ago Up 16 minutes cabot_beat_1
1850d9a11ef7 cabot:web " ./docker-entrypoint." 16 minutes ago Up 16 minutes 0.0.0.0:5001-> 5001/tcp cabot_web_1

9e1b8045bf0e postgres:alpine " docker-entrypoint.sh" 16 minutes ago Up 16 minutes 5432/tcp cabot_db_1
That’ s it! We' ve our Cabot monitoring tool up and running now. You can access it from the web interface using the web URL > > http://Server IP:5001 or Hostname:5001.
Create a Super User account.
You are now into the Cabot application.
