DNS config for NSQD
Dynamically configure nsqd with IP addresses from DNS A-record. Read more about NSQ dynamic service discovery with DNS records.
Set up
- Create a private zone in AWS Route 53
- Create a Record Set with an address
- Add an A record w/ a list of IP's for
nsqlookupd
Note: Step 3 should be automated. When nsqlookupd boots the IP should be automatcially added to the above A record.
Command Line Options
-config-http-address=: <addr>:<port> of the HTTP config endpoint
-lookupd-dns-address=: <addr> of DNS A record that provides nsqlookupd IP Addresses
-lookupd-tcp-port=4160: <port> of nsqlookupd TCP address
Run
docker run --rm -it harlow/nsqd-discovery \
--lookupd-dns-address $LOOKUPD_DNS_ADDRESS \
--config-http-address $CONFIG_HTTP_ADDRESS
Development
After verifying the desired functionality build the docker image in preparation for deployment.
The image is around ~5MB. Thanks to this post from Travis Reeder.
