This is a base Onbuild image for quickly setting up confd containers.
Create Dockerfile
FROM rancher/confd-base
VOLUME /my/config/paths
Create conf.d and templates directories and add files
mkdir templates conf.d
Add config toml files to conf.d and the template in the templates directory. When you are ready to create your image build:
docker build --rm -t myimage .
The resulting image will be configured to run confd with the files in these directories.
Note: Remember to write your files to an exported volume, otherwise the configs might not help you.
