What would be the best way to install yarn on amazon/aws-cli:2.7.4 image?

[Yusuf Doctor]

I need to deploy a serverless file but before deploying we need to run 'yarn install'. I have tried different ways to install yarn but keep facing errors.

Installing directly with yum doesn't work, it gives an error 'no package yarn found'

I tried installing using script but that also didn't work,

- curl -sL https://dl.yarnpkg.com/rpm/yarn.repo -o /etc/yum.repos.d/yarn.repo

- yum install yarn -y

Is there a way to install without needing to install npm?

@Yusuf Doctor hi. You can try to use serverless-deploy pipe with preexecution scripts.

Example passing preexecution hook script file (file should have at least read and execute permissions):

script:
  - echo 'npm install serverless-additional@2.*' > .my-script.sh
  - chmod 005 my-script.sh
  - pipe: atlassian/serverless-deploy:1.2.0
    variables:
      AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
      AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
      PRE_EXECUTION_SCRIPT: '.my-script.sh'
