Docker container that uses docker-gen and Google Cloud DNS via gcloud to automatically manage (add/remove) DNS records based on Docker container info of container host.
Ready for alpha testing. Ready for Rancher catalog stack inclusion alpha testing.
Any container that has VIRTUAL_HOST env set will be added to your Google Cloud DNS managed zone. You will need to install your valid per host credentials in /var/log/dockprox/gc-credentials.json You need to set two container ENV vars as shown below. One for the Google CLoud project and another for the DNS zone to be managed.
docker build -t unxsio/gcdns-genbot .
#install gc-credentials.json in /var/local/dockprox on host
docker run --restart unless-stopped --name gcdns-genbot --env cGCDNSProject=adhoc-dev --env cGCDNSZone=sistemasadhoc-com\
-v /var/run/docker.sock:/var/run/docker.sock:ro -v /var/local/dockprox:/var/local/dockprox -d unxsio/gcdns-genbot
Use docker ps|grep gcdns-genbot to get your container short tag (here we use ccb87c3fbc3c for examples below)
Check ENV, make sure cGCDNS vars are correct:
docker exec ccb87c3fbc3c env
Check credentials, one must be ACTIVE:
docker exec ccb87c3fbc3c /google-cloud-sdk/bin/gcloud auth list
Check DNS environment, must show cGCDNSZone:
docker execdocker exec /google-cloud-sdk/bin/gcloud dns managed-zones list
Check your zone records using cGCDNSZOne (here we use sistemasadhoc-com as an example):
docker exec ccb87c3fbc3c /google-cloud-sdk/bin/gcloud dns record-sets list --zone=sistemasadhoc-com
Check last docker-gen changes (already exist errors are normal):
docker exec ccb87c3fbc3c cat /tmp/gcdns.sh.log
