Can you define optional docker-compose services? -


is there way define docker compose service such brought up when explicitly request it?

that say:

docker-compose

would not start it, but

docker-compose optional_service

would.

one way achieve define optional service in different compose file. start optional service, run:

$ docker-compose -f docker-compose.yaml -f optional-service.yaml

for example, if have docker-compose.yaml file looks like:

version: '2.1' services:   lb:     image: nginx:1.13              db:     image: redis:3.2.9

i can extend optional-service.yaml looks like:

version: '2.1' services:   busy:     image: busybox

notice both compose files must use same compose file version.

you can read more in compose documentation.

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
