docker pull infracloudio/csvserver:latest docker pull prom/prometheus:v2.22.0

1.Run the container image infracloudio/csvserver:latest in background and check if it's running. docker run -d --name csvserver infracloudio/csvserver:latest

2.If it's failing then try to find the reason, once you find the reason, move to the next step. docker logs csvserver the input file is missing

3.Write a bash script gencsv.sh to generate a file named inputFile whose content looks like: bash script to create inputFile #!/bin/bash

if [[ $# -ne 2 ]]; then echo "Usage: $0 [start_index] [end_index]" exit 1 fi

start=$1 end=$2

if (( start >= end )); then echo "Error: start index must be less than end index" exit 1 fi

for (( i=start; i<=end; i++ )) do rand_num=$(( $RANDOM % 1000 )) echo "${i}, ${rand_num}" >> inputFile done

4.Run the container again in the background with file generated in (3) available inside the container (remember the reason you found in (2)). docker run -d --name csvserver -v $(pwd)/inputFile:/csvserver/inputdata infracloudio/csvserver:latest

5.Get shell access to the container and find the port on which the application is listening docker exec -it csvserver sh-4.4# netstat -tuln exit docker stop csvserver docker rm csvserver

6.Same as (4), run the container and make sure,The application is accessible on the host at http://localhost:9393 ,Set the environment variable CSVSERVER_BORDER to have value Orange. docker run -d --name csvserver -p 9393:9300 -v $(pwd)/inputFile:/csvserver/inputdata -e CSVSERVER_BORDER=Orange infracloudio/csvserver:latest
