AWS beanstalk can't update environment

Question

In our node js backend we had to install chromium, which cannot be installed via package.json. After some work we somehow managed to make it work on deploy with these scripts:

To install chromium:
sudo amazon-linux-extras install epel -y
sudo yum install chromium -y

To execute the previous script we put the following file under .ebextensions:
files:
  "/opt/elasticbeanstalk/hooks/appdeploy/pre/10_install_chromium.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      /var/app/current/install-chromium.sh

"/var/app/current/install-chromium.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      sudo amazon-linux-extras install epel -y
      sudo yum install chromium -y

container_commands:
  01_add_execute_permission:
    command: "chmod +x /var/app/current/install-chromium.sh"
  02_run_install_script:
    command: "/var/app/current/install-chromium.sh"

The problem we face now is that this does not work when we try to update the environment, like for instance when we try to update the environment variables, because apparently the process is different

Answer

Hello,

In order to troubleshoot your platform hook and .ebextensions config files, I would like to recommend you to share the log from your EB environment.

You can get logs by following instructions from our official document [1], or accessing to EC2 instances directly and checking log files under '/var/log' path.

Also, hook file under '"/opt/elasticbeanstalk/hooks/appdeploy/pre' path executes before the deployment of your application, so please consider other hook files.

Regards,
