如何使用环境变量在 Elastic Beanstalk EB 上运行 sequelize db:migrate?如何在容器命令中访问 .env 变量? [英] How to run sequelize db:migrate on Elastic Beanstalk EB with env vars? How to access .env vars in container commands?

问题描述

How can I run sequelize db:migrate on ElasticBeanstalk with env vars?

Running sequelize migrate fails since it cannot find the .env file.

{ Error: ENOENT: no such file or directory, open '.env'

my master.config looks like:

container_commands:
  00_node_binary:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
  00_npm_binary:
      command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
  01_migrations:
    command: npm run migrate
    leader_only: true

and my package.json contains

"migrate": "node_modules/sequelize-cli/bin/sequelize db:migrate"

解决方案

Don't forget to include the first two commands, the file migration.config that worked for me in .ebextensions looks like this

container_commands:
  00_node_binary:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
  00_npm_binary:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
  50-run-database-migrations:
    command: "./node_modules/.bin/sequelize db:migrate"
    leader_only: true

It looks like the ./node_modules/.bin/sequelize uses /usr/bin/env/node and will give you the following error:

/usr/bin/env: node: No such file or directory

Because apparently node is called nodejs... the first two container commands will take care of that.
