Simple nginx container to verify functionality of container secrets in spinup, or in docker

docker build .

example running container docker run -it --env API_HOST=localhost --env API_PORT=1234 --env testsecret=blah --name nginxcontainerimage f4a8469b5de7

dockerhub push

The dockerhub userID and repository name:

• mydockerhubuser/createsecrets

docker login --username=mydockerhubuser

docker build . && docker rm friendlyimagename

docker tag 1c4394e94846 mydockerhubuser/createsecrets:nginxenv

docker push mydockerhubuser/createscripts:nginxenv

example running container

docker run -it --env API_HOST=localhost --env API_PORT=1234 --env testsecret=blah --name friendlyimagename f4a8469b5d e7

get the container ID so you can connect to it and verify the image has the files modified with the ENVs docker ps

exec into the container docker exec -it c9d631a99c95 bash|ash

check out files cat /etc/nginx/conf.d/default.conf resolver 127.0.0.11 valid=10s; # recover from the backend's IP changing
