JSON value substitution in bitbucket pipeline

Question

I have a JSON file "appSettings.json" which has the following content:

{
  "Branch": {
    "Name": "test"
  },
}

My question is, how do I set the value "Branch.Name" to something else when running the bitbucket pipleline?

Answer 1

figured it out after checking this question.

- apt-get update
- apt-get install -y jq # install jq
- tmp=$(mktemp)
- jq '.Branch.Name = "prod"' appsettings.json > "$tmp" && mv "$tmp" appsettings.json

Answer 2

You can use standard Bash/Shell commands to do a 'Find and Replace' inside a text file:

Use sed

sed -i -e 's/"test"/"prod"/g' appSettings.json

# Delete the unwanted backup file, created by sed
if [ -e appSettings.json-e ]
then
    rm appSettings.json-e
fi

Use echo with Bash string substitution

Use this if you need to replace with special characters like "/" and "\", which sed cannot handle.

file_contents=$(< appSettings.json )
echo "${file_contents//\"test\"/\"prod\"}" > appSettings.json
