now that i have a slimmed down image from the previous post lets get it up and running as a service. i did not do any reading before trying this so i took the working docker run example from earlier post and jumped straight in with…

docker service create -p 5001:443 \
   -e ASPNETCORE_URLS="https://+443" \
   -e ASPNETCORE_Kestrel__Certificates__Default__Password="crypticpassword" \
   -e ASPNETCORE_Kestrel__Certificates__Default__Path=/https/GuidMaker.pfx \
   -v ${HOME}/https:/https \
   --name guidmaker \
   legobuff/guidmaker:arm32

and quickly recieved:

unknown shorthand flag: 'v' in -v
See 'docker service create --help'.

okay, so to the documentation… where I find that -v ${HOME}/https:/https needs to be swapped out with --mount type=bind,source=${HOME}/https,destination=/https, trying again…

overall progress: 1 out of 1 tasks 
1/1: running   [==================================================>] 
verify: Service converged

so that works, though after reading the documentation looks like docker service “prefers” to use the full arguments so lets try again with…

docker service create --name guidmaker \
   --publish published=5001,target=443 \
   --env ASPNETCORE_URLS="https://+443" \
   --env ASPNETCORE_Kestrel__Certificates__Default__Password="crypticpassword" \
   --env ASPNETCORE_Kestrel__Certificates__Default__Path=/https/GuidMaker.pfx \
   --mount type=bind,source=${HOME}/https,destination=/https \
   legobuff/guidmaker:arm32

Error response from daemon: rpc error: code = InvalidArgument desc = port '5001' is already in use by service 'guidmaker' (d0oudeiu51kuj26cemtcesflk) as an ingress port

oops, i forgot to remove the service before creating it again… docker service rm guidmaker takes care of that and trying again, success. now a docker service ls gives…

ID                  NAME                MODE                REPLICAS            IMAGE                       PORTS

lets see if it scales…

docker service scale guidmaker=6
guidmaker scaled to 6
overall progress: 6 out of 6 tasks 
1/6: running   [==================================================>] 
2/6: running   [==================================================>]

4/6: running   [==================================================>] 
5/6: running   [==================================================>] 
6/6: running   [==================================================>] 
verify: Service converged

and…

docker service ls

double checking by hitting the service at https://localhost:5001/api/guid, and 👍
