How to build Insights Docker Image (Linux)

Step - by - step guide to how to Install Insights on Linux using Docker

Prerequisite:

Install Docker:

On RHEL/Centos7:

yum update
yum install yum-utils
yum-config-manager --enable rhui-REGION-rhel-server-extras
yum install docker
systemctl start docker
systemctl status docker
systemctl enable docker (start docker at system boot)

On Ubuntu:

apt-get update
apt-get upgrade
apt-get install docker.io
systemctl start docker
systemctl enable docker

For docker commands please visit - https://docs.docker.com/edge/engine/reference/commandline/docker/

Build Docker Image:

UIEngineAgentDaemon

Build Image:

git clone -b dockerImage https://github.com/CognizantOneDevOps/Insights.git
cd Insights/dockerImageFiles/UIEngineAgentDaemonImage

Dockerfile
config.env
insights_wrapper.sh

3. Convert files format to UNIX format : dos2unix *

4. Update config.env with the below specified values.

config.env

Variables	Details
hostIP	host machine IP where you are running docker container which will start rabbitmq,grafana and InsightsUI in this given hostIP
neo4jIP	IP of Neo4j
postgresIP	IP of PostgreSQL
elassticIP	IP of ElasticSearch

5. Execute the docker build command where Dockerfile located.
Syntax: docker build -t reponame:tag .
Command: docker build -t infra.cogdevops.com:8090/onedevopsinsights:<version> .

6. To push the built image to repo.

docker login -u <username> -p <password> infra.cogdevops.com:8090

docker push infra.cogdevops.com:8090/onedevopsinsights:<version>

List docker images: docker images

To run UIEngineAgentDaemon docker container: Insights Docker Installation

Run docker containers EngineJar/Deploy war (Obsolete):

Engine Jar

Create Images:
Create a directory and copy files from

dockerfile
insightsJar.sh
config.env

Execute the following command:

dos2unix *

This command will convert downloaded files to UNIX format

Overview of property to be set in config.env file:

Variables	Details
postgresIP	IP of PostgreSQL
neo4jIP	IP of Neo4j
mqIP	IP of Rabbit MQ
insightsConfig	URL of InSightsConfig.zip
jdkURL	URL of Java JDK
jarURL	URL for updated PlatformEngine.jar

Update config.env variables and run the below command from the path of copied files.

docker build -t tag_name .

Example : docker build -t insights/engine .

The above command create an image with unique id which will be used to create the containers.
Check the list of images created by,

docker images

Create containers -
Run the image built to create containers

docker run -dit --env-file config.env imageID

Let ' e10aca6729db ' be the imageID created.

Example :   docker run -dit --env-file config.env e10aca6729db

This command will create a container and return a code, details of the container can be viewed by running the command ' docker ps '

-dit runs the container in detached mode. For interactive mode use -it.

Ensure that docker run command is executed from the path where config.env is present.

To list the containers -
docker ps [ For active containers ]

docker ps -a [ For all containers ]

Check logs of container -
docker logs containerID

Let '614bcc4546de' be the containerID created,

Example : docker logs 614bcc4546de

Connect to the container -
User can get into the newly created container where jar is running by ,

docker exec -it containerID bash

Example : docker exec -it 614bcc4546de bash

Deploy war

Create Images -
Make a directory and copy files from

dockerfile
insightsUI.sh
config.env

Execute the following command:

dos2unix *

This command will convert downloded files to UNIX format

Make sure that you have connection with the instance where you have other components ( Postgres, Rabbitmq, Neo4j )

Overview of variables to be set in config.env

Variables	Details
elasticIP	IP of Elastic Search
postgresIP	IP of PostgreSQL
neo4jIP	IP of Neo4j
mqIP	IP of Rabbit MQ
ldapUrl	URL of LDAP
bindDN	Bind DN of LDAP
bindPassword	Password for Bind DN
searchBaseDN	Base DN for LDAP Search
jdkURL	URL of Java JDK
insightsConfigURL	URL of InSightsConfig.zip
grafanaURL	URL of Grafana
grafanaLDAP	URL of ldap.toml
grafanaDefaults	URL of defaults.ini
insightsUI	URL of InSightsUI.zip
insightsWar	URL of PlatformService.war
tomcatURL	URL of apache tomcat

Update config.env variables and run the below command from the path of copied files.

docker build -t tag_name .

Example : docker build -t insights/ui .

The above command create an image with unique id which will be used to create the containers.
Check the list of images created by,

docker images

Create containers -

Run the image built to create containers

docker run -dit -p 3000:3000 -p 8080:8080 --env-file config.env imageID ping -t localhost

Let ' e10aca6729db ' be the imageID created.

Example : docker run -dit -p 3000:3000 -p 8080:8080 --env-file config.env e10aca6729db ping -t localhost

- dit runs the container in detached mode. For interactive mode use - it.

- p helps to expose specified ports. If port is already in use, try with other port of host to connect.
Make sure that Grafana runs on 3000 by default.

To list the containers -
docker ps [ For active containers ]
docker ps -a [ For all containers ]

Check logs of container -
docker logs containerID

Let '614bcc4546de' be the containerID created,

Example : docker logs  614bcc4546de

Connect to the container -
User can get into the newly created container where jar is running by ,

docker exec -it containerID bash

Example : docker exec -it 614bcc4546de bash

Check the URLs -

Note: insightsUI.sh file fetches publicIP of the host that you are using and run Grafana, Tomcat on relevant ports of it.
If any of the container orchestration utility (like kubernetes) is used in order to run this UI image, then 'ping -t localhost' is not needed at the end of 'docker run' command

http://hostPublicIP:3000 for grafana
http://hostPublicIP:8080/app for Insights UI
