我有一个在Docker上本地运行的Rails应用程序，现在我正遵循Laurent Julliard出色的tutorial来使用Cloud Run将其部署到Google Cloud Platform。
我正在使用以下GCP服务：
后3个服务与此问题无关（我认为是??♂️）。
我的部署过程包括两个步骤：
cloudbuild.yaml 文件描述了Cloud Build构建容器所必须执行的步骤。
steps:
# Decrypt Rails Master key file
- name: gcr.io/cloud-builders/gcloud
args: ["kms", "decrypt", "--ciphertext-file=./config/master.key.enc",
"--plaintext-file=./config/master.key",
"--location=us-central1","--keyring=whale-on-rails",
"--key=rails_master_key"]
# Decrypt Whale on Rails service account credentials
- name: gcr.io/cloud-builders/gcloud
args: ["kms", "decrypt", "--ciphertext-file=./config/whale_on_rails.key.enc",
"--plaintext-file=./config/whale_on_rails.key",
"--location=us-central1","--keyring=whale-on-rails",
"--key=whale_on_rails_key"]
# Build image with tag 'latest' and pass decrypted Rails DB password as argument

# Run the web service on container startup
bundle exec rails server -e production -b 0.0.0.0 -p $PORT
最后，我正在使用以下命令来构建容器。
$ gcloud builds submit --config cloudbuild.yaml
此过程效果很好。问题出在下一步...
$ gcloud beta run deploy whale-on-rails --image gcr.io/$PROJECT_ID/whale_on_rails \ 4m 58s Ruby 2.6.5
--set-cloudsql-instances whale-on-rails-production \
--region us-central1 --allow-unauthenticated --platform managed
在此步骤中，我在终端中收到此错误：
ERROR: (gcloud.beta.run.deploy) Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable. Logs for this revision might contain more information.
然后查看Cloud Run日志，我得到了：

我的问题是，为什么会出现此错误？在漏洞处理过程中，一切看起来都很好，我已逐步按照教程进行操作（唯一的不同是，他们使用MySQL，而这里使用的是Postgres）。
