Permission Error running `npm install` on elasticbeanstalk

[sevab]

I've managed to successfully create an Elastic Beanstalk app following the documentation.

The ember app itself is zipped and deployed to S3 via ember-cli-deploy-elastic-beanstalk, which the eb server manages to successfully download and unzip, however a permission error is logged when fastboot-s3-downloader tries to run cd deploy-dist && npm install:

No FASTBOOT_REDIS_HOST or FASTBOOT_REDIS_PORT provided; caching is disabled.

The server is able to start regardless, because ember-deploy includes node_modules as part of dist-deploy.zip, but it would be nice to avoid this error.

A brute force solution would be to have fastboot-s3-downloader run npm install with sudo, but that probably should be avoided.

Would appreciate any help if anyone dealt with this issue as well.

Things tried so far that didn't work:

• mkdir ~/.npm-global && NPM_CONFIG_PREFIX=~/.npm-global
• not including node_modules as part of ember deploy dist-deploy.zip

The solution is to add permissions to the nodejs user, so it can access /tmp/.npm. In ElasticBeanstalk this can be achieved by adding a file .ebextensions/00_change_npm_permissions.config with the following contents:

files:
  "/opt/elasticbeanstalk/hooks/appdeploy/post/00_set_tmp_permissions.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      chown -R nodejs:nodejs /tmp/.npm

Then committing it into the repo and making an eb deploy.

I can submit a documentation PR regarding this.

Thanks @sevab - this was very helpful :)

Hi @sevab, where should I put .ebextensions/00_change_npm_permissions.config file?

[sevab]

@IAmJulianAcosta in the .ebextensions directory at the root of your elasticbean project.

[cubbuk]

Thanks @sevab it was very helpful indeed.

Thanks! We had the same issue with the "sharp" library and that fixed the problem. Basically it would install correctly when launching a new environment, but not when doing an eb deploy. Leading to

51771 error code ELIFECYCLE
51772 error [email protected] install: `node-gyp rebuild`
51772 error Exit status 1
51773 error Failed at the [email protected] install script 'node-gyp rebuild'.

The permission config fixed it.

Unrelated to fastboot, I had also permission denied errors when running node-gyp. I found out that while npm install was run by root, node-gyp invocations it started were run by the user ec2-user, which obviously lacked access to the root-owned directories /tmp/deployment/application/node_modules/, /tmp/.npm, and /tmp/.config.

My solution was to instruct npm to use the same user (i.e. root via unsafe-perm=true) - see https://stackoverflow.com/questions/46001516/beanstalk-node-js-deployment-node-gyp-fails-due-to-permission-denied/46001517#46001517

I wonder whether it would work also in this ☝️ case, instead of changing permissions on /tmp?

[klemensz]

@jakubholynet Interesting... actually I need to revert my comment from above, the permission config didn't fix the error (only temporarily). In the end moving away to another library that doesn't need node-gyp was the "solution" for us.

[nnn406]

@jakubholynet I faced with the similar problem, but I know that starting npm install from root it's not the best idea, so I've made following changes in my scripts

sudo -u ec2-user -H npm install --production

And then problem has been gone

Use .npmrc file to configure unsafe-perm to true for node-gyp commands on aws.

This does not work. Everyone has pointed to this link https://stackoverflow.com/questions/46001516/beanstalk-node-js-deployment-node-gyp-fails-due-to-permission-denied/46001517#46001517. However setting that unsafe-perm to true still doesn't work.

[klemensz]

@nnnikolay The documentation says that Elastic Beanstalks runs npm install --production by default: https://docs.aws.amazon.com/de_de/elasticbeanstalk/latest/dg/nodejs-platform-packagejson.html

Hi there, I had the same issue, tried with .npmrc file that solved it. After a month got again a permission issue on /tmp/.npm, and /tmp/.config. It happen to be that those folders where suddenly missing from the environment. I needed to change the elastic beanstalk deployment configuration to "immutable" which force deployment from scratch. And that solved the issue. Hope it helps...

[bthiban]

If you do not already have a .ebextensions folder in the root of your project, create it. Then create a file in .ebextensions named 01_fix_permissions.config. EB knows to run files in the .ebextensions folder at the beginning of the deployment in order, which is why the “01” prefix is used. Inside this file enter the following:

files:
  "/opt/elasticbeanstalk/hooks/appdeploy/pre/49_change_permissions.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      sudo chown -R ec2-user:ec2-user tmp/
      set -xe
      /opt/elasticbeanstalk/bin/healthd-track-pidfile --proxy nginx

Which script?

[akashgangrade]

Add a file named .npmrc to the application with the content:

unsafe-perm=true Now use the following command before pushing it to ElasticBeanStalk:

git add .npmrc
 git commit -m"EB issue fix"

Now deploy your code. It should work.
