How to insert new line after a specific character in scripts?

Hi,


I'm trying to add a new line after finding a specific String.

That is my string:
volumes:
-
Code:
${DIR_WORK}/loadbalancer/html:/var/www/html


and I want to change that file to:
volumes:
-
Code:
${DIR_WORK}/loadbalancer/html:/var/www/html
extra_hosts:
      - "hostname:192.168.1.4"


That my code:



Code:
 lastLine="{DIR_WORK}/loadbalancer/html:/var/www/html"
 extraHost="extra_hosts:"
 sed 's~'"${lastLine}"'~a\'"${extraHost}"'~' $file


but that do nothing
