Невозможно инициализировать базу данных с помощью менеджера эволюции схемы при запуске докера.Мой файл Docker выглядит следующим образом
FROM postgres:10-alpine
WORKDIR /opt/ext-api-db
COPY . .
RUN apk add py-pip ruby ruby-rdoc
RUN gem install schema-evolution-manager && \
pip install awscli
RUN cp docker-entrypoint-initdb.d/* /docker-entrypoint-initdb.d
EXPOSE 5432
docker-entrypoint-initdb.d содержит один сценарий инициализации
set -e
psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" <<-EOSQL
CREATE DATABASE ${POSTGRES_USER}_test;
GRANT ALL PRIVILEGES ON DATABASE ${POSTGRES_USER}_test TO $POSTGRES_USER;
EOSQL
# Applying Sem Scripts
echo
echo 'PostgreSQL initialzing Data...'
echo
"pg_ctl -o" -c listen_addresses='localhost'" -D "$PGDATA" -w restart"
sem-apply --url postgresql://$POSTGRES_USER:$POSTGRES_PASSWORD@localhost/$POSTGRES_DB
sem-apply --url postgresql://$POSTGRES_USER:$POSTGRES_PASSWORD@localhost/$POSTGRES_DB_test
При запуске контейнера Docker база данных создается нормально, но менеджер эволюции схемы говоритНевозможно подключиться к базе данных. Вот полная трассировка стека

Вот моя конфигурация docker-compose
version: "3"
services:
ext-api-db:
build:
context: .
container_name: ext-api-db
env_file: docker-compose.env
hostname: ext-api-db
networks:
- ext
ports:
- "15432:5432"
restart: unless-stopped
volumes:
- .:/opt/ext-api-db:delegated
networks:

external:
name: ext
Может кто-нибудь сказать мне, как я могу исправить эту проблему?
