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

Build Image:

1. git clone -b dockerImage https://github.com/CognizantOneDevOps/Insights.git
2. 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

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

     6. To push the built image to repo.

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

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

To run UIEngineAgentDaemon docker container: Insights Docker Installation

Create Images:
Create a directory and copy files from   https://platform.cogdevops.com/docker/EngineJarImage/

• 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:
 

  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 '

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    

Create Images - 
Make a directory and copy files from   http://platform.cogdevops.com/docker/UIWarImage/

• dockerfile
• insightsUI.sh
• config.env

Execute the following command:

     dos2unix *

This command will convert downloded files to UNIX format

Overview of variables to be set in config.env

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

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
