我有一个 minikube 设置，其中容器在启动时需要访问 npm 注册表。但是 pod 无法连接到 npm 注册表。我的印象是所有传出连接都是从 K8s 打开的。

从 pod 记录

kubectl logs <pod_name>

npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN
npm ERR! request to https://registry.npmjs.org/sequelize-cli failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2021-04-14T12_16_23_892Z-debug.log
Install for [ 'sequelize-cli@latest' ] failed with code 1

Dockerfile

FROM node:14.15.4-alpine
WORKDIR /app
COPY package.json .
RUN yarn install && yarn global add npx
COPY . .
EXPOSE 3000
ENTRYPOINT ["./entrypoint.sh"]
CMD [ "npm", "run", "start" ]

入口点.sh

#!/bin/sh
set -e           # Stop on any error
npx sequelize-cli db:migrate:all  # Run migrations
npx sequelize-cli db:seed:all     # Preload initial data
exec "$@"        # Run the command as the main container process
