NestJS / Prisma Docker 容器在 AWS Fargate 上失败

Question

我将 docker 容器中基于 nestjs 的后端部署到 AWS fargate。部署有效，容器可访问，健康检查为绿色。一切都按预期正常工作。大约 5 分钟后，出现以下错误，容器任务不再可访问并重新启动。我不知道发生了什么，我做错了什么。

这是来自 Cloudwatch 的错误日志：

这是我的 docker 文件：

FROM node:16 as build-stage

WORKDIR /app
COPY package*.json ./
COPY prisma ./prisma/

RUN npm install
COPY . .

RUN npm run build

FROM node:16

COPY --from=build-stage /app/node_modules ./node_modules
COPY --from=build-stage /app/prisma ./prisma
COPY --from=build-stage /app/resources ./resources
COPY --from=build-stage /app/package*.json ./
COPY --from=build-stage /app/dist ./dist

EXPOSE 3001
CMD [ "npm", "run", "start:prod", "--verbose"]

如果有人能帮助我，我将非常高兴和感激:) 谢谢。

您似乎收到了 SIGTERM。是否有可能您在 ECS 服务之前配置了负载均衡器并且健康检查失败（因此强制回收容器）？
