testing运行在gitlab-ci失败，因为Postgres不可见

在Docker中使用gitlab-ci的testing失败，因为Postgres服务不可访问。

在我的开发环境中，我成功地运行了testing： $docker-compose -f local.yaml run web py.test

但在gitlab中， - docker run --env-file=.env_dev $CONTAINER_TEST_IMAGE py.test -p no:sugar的命令- docker run --env-file=.env_dev $CONTAINER_TEST_IMAGE py.test -p no:sugar失败：

基本上，它不能看到Postgres服务。 Postgres is unavailable - sleeping文本Postgres is unavailable - sleeping来自Dockerfile的entrypoint.sh文件

以下是一些相关的文件：

gitlab-ci.yml

Dockerfile：

 # ... other configs here ENTRYPOINT ["compose/local/django/entrypoint.sh"] 

entrypoint.sh：

 # ..... other configs here export DATABASE_URL=postgres://$POSTGRES_USER:$POSTGRES_PASSWORD@postgres:5432/$POSTGRES_USER function postgres_ready(){ python << END import sys import psycopg2 try: conn = psycopg2.connect(dbname="$POSTGRES_USER", user="$POSTGRES_USER", password="$POSTGRES_PASSWORD", host="postgres") except psycopg2.OperationalError: sys.exit(-1) sys.exit(0) END } until postgres_ready; do >&2 echo "Postgres is unavailable - sleeping" sleep 1 done >&2 echo "Postgres is up - continuing..." exec $cmd
