Introduction:

Graphite is an open source monitoring platform used for the purpose of data visualization. Graphite has front-end and backend that can be used to get and store the data from numeric time-series to the graph format. Main purpose of graphite is to store numeric time-series data and provide the graph of the stored data when requested. So, let’s move towards the installation process.

Step 1: Update Your System

As usual we do update your system to have the latest packages installed. To do so run the below command.

sudo apt update && sudo apt upgrade -y

Once, the update finished reboot your system and move towards the next step.

sudo reboot

Step 2: Install Docker Container Engine on Ubuntu 20.04

Type the following command after the system reboot in your terminal.

sudo apt -y install vim apt-transport-https ca-certificates curl gnupg-agent software-properties-common

Now, import the docker GPG key using the below command.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

And then, add the Docker CE repository in Ubuntu system by hitting the given command.

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Finally, fire the below command to install Docker CE on Ubuntu 20.04 server.

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io

Once, the installation finished add your user to the docker group. To do so, fire the given command in your terminal.

Step 3: Running Graphite in Docker Container

As we’ve finished the installation of docker engine, now we’ll start docker container for Graphite. Here we’ll use the official docker repository for graphite.

Get the latest docker image by typing

sabi@Ubuntu20:~$ docker pull graphiteapp/graphite-statsd
Using default tag: latest
latest: Pulling from graphiteapp/graphite-statsd
df20fa9351a1: Pull complete
a30ee9926b20: Pull complete
51a4bd789783: Pull complete
9eb78f4a78c8: Pull complete
Digest: sha256:aaec5e5daadad64efb8039dd128e89dc6ac95bc129553427fca980a049d1fb40
Status: Downloaded newer image for graphiteapp/graphite-statsd:latest
docker.io/graphiteapp/graphite-statsd:latest

This image will contain the following parts.

• Nginx (Reverse proxy the graphite dashboard)
• Graphite(Front-end)
• Carbon(Back-end)
• Statsd(UDP based backend proxy)

Following default mapped ports will be used.

Graphite and Statsd should be handled carefully as they are very complex to setup. The docker image downloaded above help us to run & collect the stats in few minutes.

To see the available images type

sabi@Ubuntu20:~$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
graphiteapp/graphite-statsd latest 976c24bf0bc6 4 weeks ago 723MB

Now, create the following directories on the host system for persistent data storage.

sudo mkdir -p /data/graphite/{data,logs,conf,statsd_config}

Make sure to set the correct timezone and then run the following commands.

docker run -d \
--name graphit \
--restart=always \
-p 80:80 \
-p 2003-2004:2003-2004 \
-p 2023-2024:2023-2024 \
-p 8125:8125/udp \
-p 8126:8126 \
-v /data/graphite/data:/opt/graphite/storage \
-v /data/graphite/conf:/opt/graphite/conf \
-v /data/graphite/statsd_config:/opt/statsd/config \
-v /data/graphite/logs:/var/log \
-e GRAPHITE_TIME_ZONE='Asia/Karachi' \
graphiteapp/graphite-statsd

Verify the status of graphite container

sabi@Ubuntu20:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
420150f994b9 graphiteapp/graphite-statsd "/entrypoint" About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 0.0.0.0:2003-2004->2003-2004/tcp, 2013-2014/tcp, 8080/tcp, 0.0.0.0:2023-2024->2023-2024/tcp, 0.0.0.0:8126->8126/tcp, 8125/tcp, 0.0.0.0:8125->8125/udp graphit

If you face any error, refer to the logs

docker logs -f graphite

Output:

,,..

30/11/2020 01:24:26 :: [listener] MetricLineReceiver connection with 127.0.0.1:57478 closed cleanly

As by default, statsd is listening to 8125 UDP port,you can change it to tcp port if you want. To do so, you’ve to set the environment variable STATSD_INTERFACE to TCP port while running the container.

Step 4: Access Graphite Web Dashboard

Access the Graphite web interface by typing server IP.

Use the pre-defined credentials to login.

User:root
Pass:root

For security reasons, change the default credentials, by typing IP/admin/auth/user/1/

You’ll get success message of password change.

Update Your System

Hit the given command in your terminal to update your system.

sudo apt -y update

Step 1: Prepare Your Nodes

To prepare nodes, you’ve to configure hosts files on each host. In this guide I’m going to use one Manager node and 2 worker nodes.

sudo nano /etc/hosts

And add the Ip’s of your hosts.

192.168.1.10 manager
192.168.1.11 worker-1
192.168.1.12 worker-2

Save & close the file.

Verify that you can ping all the hosts using hostname instead of IP’s.

Step 2: Install Docker CE on Ubuntu 20.04

Install the Docker CE on the hosts. Hit the following command to install the required dependencies for Docker CE on Ubuntu 20.04.

sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common

Then add the Docker CE repository and GPG key on your hosts.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Once done, update the packages.

sudo apt update

Double check that you’re going to install Docker CE from the official repository of Docker.

root@ubuntu20:~$ sudo apt-cache policy docker-ce
docker-ce:
Installed: (none)
Candidate: 5:19.03.13~3-0~ubuntu-focal
Version table:
5:19.03.13~3-0~ubuntu-focal 500

5:19.03.9~3-0~ubuntu-focal 500
500 https://download.docker.com/linux/ubuntu focal/stable amd64 Packages

Verify the status of Docker CE.

root@ubuntu20:~$ sudo systemctl status docker
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: active (running) since Sat 2020-10-17 16:28:08 EAT; 57s ago

Tasks: 8
Memory: 37.5M
CGroup: /system.slice/docker.service
└─2807 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

And add your user to docker group.

sudo usermod -aG docker ${USER}

Step 3: Create Docker Swarm Cluster on Ubuntu 20.04

First start the Docker Swarm on the manager node and then start add the worker nodes to the cluster. To start docker swarm on manager node, type the given command in your terminal.

Swarm initialized: current node (fsuaqqpihi2eabmmq8gldzhpv) is now a manager.
To add a worker to this swarm, run the following command:
sudo docker swarm join --token SWMTKN-1-018kvdektwa74z8fajb5c1u6jyz6qfk4ood8u4qotw7go9jj0p-cfpnh7omy86xcgoh45vau2kaj 192.168.1.10:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

From the above result, copy the token “Join –token” command to add the worker nodes to the manager node. Here’s how you can add.

sudo docker swarm join --token SWMTKN-1-13xo81gxpb3ttjh5e335pfrmz9fbnliikgfys7u8l4r8k4m575-2gsjwjs3y1i4kgeua2yu840hw 192.168.1.10:2377
This node joined a swarm as a worker.

Verify that worker nodes are added to the manager node.

sudo docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS ENGINE VERSION
etx5xc5guzftmsqx4naqwvump worker-02 Ready Active 19.03.13
xop4jvrkywz4ldsgwqmfacssc * manager Ready Active Leader 19.03.13
bghrkp7ll1b9lb0ikv8x51gzy worker-01 Ready Active 19.03.13

Step 4: Deploy Application in the Cluster

Now, create the service Nginx web server to run on the port 80 & expose it to the port 8080 on the host. To do this type

root@ubuntu20:~$ sudo docker service create --name web-server --publish 8080:80 nginx:1.13-alpine
pq5txw0p9c1qcjrrl2lw3mh5p
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]
verify: Service converged

Verify the status of created service using.

sudo docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
pq5txw0p9c1q web-server replicated 1/1 nginx:1.13-alpine *:8080->80/tcp

Step 5: Replicas & Scale the Service

You’ve to make replicas of the web-server service in order to access it on the manager and the worker nodes.

sudo docker service scale web-server=3
web-server scaled to 3
overall progress: 3 out of 3 tasks
1/3: running [==================================================>]
2/3: running [==================================================>]
3/3: running [==================================================>]
verify: Service converged
Verify the created service replicas.

sudo docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
pq5txw0p9c1q web-server replicated 3/3 nginx:1.13-alpine *:8080->80/tcp

You can access the service from the web-browser of any host added with the help of IP address and port number like below:
192.168.1.10:8080

So, this is how you can install Docker Swarm on Ubuntu 20.04.

Before proceeding towards the installation procedure, make sure your system has a static IP configured.

Step 1: Update Your System

Before installing any new package, make sure your system is up-to date.

sudo apt -y update

Step 2: Download & Install the BIND DNS Server

Run the below command to install the bind dns server and required packages.

sudo apt install -y bind9 bind9utils bind9-doc dnsutils

Step 3: Configure DNS Server

Main configuration directory of DNS is located at /etc/bind.

Global DNS configuraiton file can be found at /etc/bind/named.conf that can’t be used for local DNS. For local DNS, /etc/bind/named.conf.local is used.

Create Zones

Edit the local DNS file with your favourite editor.

sudo nano /etc/bind/named.conf.local

And then create forward & reverse zones for your domain. Here I’ll create for osradar.com as seen below:

zone "osradar.local" IN { // Domain name

type master; // Primary DNS

file "/etc/bind/forward.osradar.local.db"; // Forward lookup file

allow-update { none; }; // Since this is the primary DNS, it should be none.

};

That was for the forward zone. Now, we’ll add for reverse zone.

zone "10.16.172.in-addr.arpa" IN { //Reverse lookup name, should match your network in reverse order

type master; // Primary DNS

file "/etc/bind/reverse.osradar.local.db"; //Reverse lookup file

allow-update { none; }; //Since this is the primary DNS, it should be none.

};

10.16.172.in-addr.arpa is the zone name of reverse DNS. (If network is 172.16.10.0, the name will be reversed as in 10.16.172).

Step 4: Configure Bind DNS Zone Lookup Files

As described earlier, the zone lookup files have the DNS records of the forward & reverse zones. So, we’ll configure them.

For Forward Zone Lookup File

Now, copy the sample forward zone lookup file to the file called forward.osradar.local.db located at /etc/bind directory.

sudo cp /etc/bind/db.local /etc/bind/forward.osradar.local.db

Now, edit the above file.

sudo nano /etc/bind/forward.osradar.local.db

$TTL 604800
@ IN SOA ns1.osradar.local. root.ns1.osradar.local. (
3 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
;@ IN NS localhost.
;@ IN A 127.0.0.1
;@ IN AAAA ::1

;Name Server Information

@ IN NS ns1.osradar.local.

;IP address of Name Server

ns1 IN A 172.16.10.2

;Mail Exchanger

osradar.local. IN MX 10 mail.osradar.local.

;A – Record HostName To Ip Address

www IN A 172.16.10.3
mail IN A 172.16.10.4

;CNAME record

ftp IN CNAME www.osradar.local.

For Reverse Zone Lookup File

Simply perform the above actions for reverse zone lookup file.

sudo cp /etc/bind/db.127 /etc/bind/reverse.osradar.local.db

And then modify the content.

sudo nano /etc/bind/reverse.osradar.local.db

;
; BIND reverse data file for local loopback interface
;
$TTL 604800
@ IN SOA osradar.local. root.osradar.local. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;

;Name Server Information

@ IN NS ns1.osradar.local.
ns1 IN A 172.16.10.2

;Reverse lookup for Name Server

2 IN PTR ns1.osradar.local.

;PTR Record IP address to HostName

3 IN PTR www.osradar.local.
4 IN PTR mail.osradar.local.

Step 5: Verify Bind DNS Syntax

Hit the given command to verify the syntax of bind DNS it’ll return to the shell if everything is ok.

sudo named-checkconf

Fire the below commands to check the syntax for forward & reverse zones respectively.

sudo named-checkzone osradar.local /etc/bind/forward.osradar.local.db
sudo named-checkzone 10.16.172.in-addr.arpa /etc/bind/reverse.osradar.local.db

You’ll see the similar output respectively.

#####forward zone file
OK
#####reverse zone file
zone 10.16.172.in-addr.arpa/IN: loaded serial 1
OK

Finally, restart & enable BIND services.

sudo systemctl restart bind9
sudo systemctl enable bind9

Step 6: Test DNS Server On Ubuntu 20.04

We can change the DNS server on any of client machine to our newly created server. Every OS has different DNS settings. In Ubuntu type

sudo echo "nameserver 172.16.10.2" >> /etc/resolv.conf

Now, type dig command along with your domain name to test the DNS server.

root@ubuntu20:~# dig www.osradar.local

; <<>> DiG 9.16.1-Ubuntu <<>> www.osradar.local
;; global options: +cmd
;; Got answer:
;; WARNING: .local is reserved for Multicast DNS

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 65241

And to test the reverse DNS, type

root@ubuntu:~# dig -x 172.16.10.3

; <<>> DiG 9.16.1-Ubuntu <<>> -x 172.16.10.3
;; global options: +cmd
