spring-boot-app-config

Files for setting up spring-boot application configuration

If you currently have your application secrets either:

• hardcoded in the Java
• hardcoded in an application.properties
• in application.properties which is in .gitignore

then the four files in the subdirectory config in this repo are just what you need.

env.sh
setHerokuEnv.py
localhost.json.SAMPLE
heroku.json.SAMPLE

To use these files:

1. Clone this repo as a sibling of your repo
2. cd into your repo, and then do:

   cp ../spring-boot-app-config/config/* .
   

3. Then, add these files to your .gitignore

   localhost.json
   heroku.json
   

4. Commit these four new files to your repo (and the changes .gitignore)

Using the files on localhost

1. cp localhost.json.SAMPLE localhost.json

2. Edit localhost.json with the values that you need.

3. Execute source env.sh OR . env.sh

   Those both do the same thing. NOT the same as ./env.sh

   The space between . and env.sh is on purpose.

   This defines an environment variable SPRING_APPLICATION_JSON which has property values that override the ones in your src/main/resources/applicaiton.properties or src/main/resources/application.yml with new values.

   Those are the values you use when running on localhost.

   The file localhost.json.SAMPLE should contain "fake data" for all the values you need, and the README.md should explain how to set up real values (e.g. how to set up github oauth, or firebase credentials, or google oauth, or an mlab database, etc. etc.)

Using the files to run on heroku

1. Copy from heroku.json.SAMPLE to heroku.json

2. Edit the file to set the values for heroku

3. Run ./setHerokuEnv.py --app name-of-your-herokuapp

   If you get a permission error, do this first:

   chmod u+x setHerokuEnv.py`
   

   This sets the config variables on Heroku to the values in your heroku.json. You can see those value in the Heroku dashboard config vars.
