sed to edit yaml file with individual values to each key-CodePudding

I have a yaml file and shell script to edit the values of yaml file.

#YAML
UI:
  repo: my-repo-1
  imageTag: ui-image:v1
DB:
  repo: my-repo-2
  imageTag: db-image:v1

#!/bin/bash
sed -i "/^\([[:space:]]*imageTag: \).*/s//\1$1/" test.yaml

On running the script to change the tag of UI with ./script.sh ui-image:v2 is changing the imageTag of both UI and DB with value "ui-image:v2".

How can I make a change in the script so that I can pass individual tag to both UI and DB

CodePudding user response：

You can limit the replacement for $1 to "from UI: to imageTag:" and similarly for DB: and $2:

sed -i -e "/^UI:/,/imageTag:/{/^\([[:space:]]*imageTag: \).*/s//\1$1/}" \
       -e "/^DB:/,/imageTag:/{/^\([[:space:]]*imageTag: \).*/s//\1$2/}" \
       test.yaml
