Не работает связь между двумя контейнерами api и front?

получаю ошибку вида ) контейнеры находятся в одной сети)
cURL error 6: Could not resolve host: l.mkk.api.loc

или

Connection timed out after 5000 milliseconds (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for host.docker.internal/api/references/credit-products?where%5Bshow_in_lk%5D=1&columns%5B0%5D=id&columns%5B1%5D=name&columns%5B2%5D=min_amount&columns%5B3%5D=max_amount&columns%5B4%5D=min_period&columns%5B5%5D=max_period&columns%5B6%5D=percent

в хостах прописано след

127.0.0.1 l.mkk.api.loc
127.0.0.1 l.mkk.lk.loc
127.0.0.1 host.docker.internal
127.0.0.1 gateway.docker.internal

[сергей кузьмин]

друг с другом/ друга контейнеры соединяются / находят по имени сервиса без доменного суффикса (pgsq, nginx,app)

[sergey228_G]

сергей кузьмин, подскажи пожалуйста как соеденить ) чтобы эта связка заработала

[сергей кузьмин]

код в котором соедияются надо весь править . вот элементарный кластер с postgres и еще одним контейнером который ничего кроме healthcheck не делает

Dockerfile

  example:

в HEALTHCHECKс postgresсоединяются по имени potsgres
в initdb/1.sql просто
create table sometable(id int);
