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 vars？

Question

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"

Answer 1

Edit:

I just found out what's going on with environment variables. Try running the migration script without npm . It'll be something like:

./node_modules/.bin/sequelize db:migrate

This way, you'll get all the environment variables as you expect.

Old answer:

Are you sure your .env file is committed to your git repo? In general, it's not a good idea to commit a .env to git and use it in production. You should instead set environment variables in your Elastic Beanstalk dashboard under Software Configuration .

You could also use the eb command line utility as documented here .

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.

See https://github.com/nodejs/node-v0.x-archive/issues/3911 for further reference

I resolve this error through running command in .ebextension/config_file.sh node vsersion is same which is using in the EB console

files: "/opt/elasticbeanstalk/hooks/appdeploy/pre/config_file.sh":

mode: "000755"
owner: root
group: root
content: |
  #!/bin/bash
  
  curl --silent --location https://rpm.nodesource.com/setup_12.x | sudo bash -
  
  sudo yum -y install nodejs

---

then

run command on terminal in your app directory:

./node_modules/.bin/sequelize db:migrate

its work for me!!

Answer 4

None of the solutions worked for me. What worked was lazartravica 's answer on the following page:

https://github.com/sequelize/sequelize/issues/12913#issuecomment-782254695

TLDR:
Don't run npm install in the Deploy step, this is both a security and a performance issue. Run node_modules/sequelize-cli/lib/sequelize db:migrate in the Build step to fix the issue.
