Devfile commands

Currently, CodeCatalyst only supports exec commands in your devfile. For more information, see Adding commands in the Devfile.io documentation.

The following example shows you how to specify exec commands in your devfile.

commands:
  - id: setupscript
    exec:
      component: test
      commandLine: "chmod +x script.sh"
      workingDir: /projects/devfiles
  - id: executescript
    exec:
      component: test
      commandLine: "./projects/devfiles/script.sh"
  - id: updateyum
    exec:
      component: test
      commandLine: "yum -y update --security"

After you're connected to your Dev Environment, you can execute defined commands through the terminal.

/aws/mde/mde command <command-id>
/aws/mde/mde command executescript

For long running commands, you can use the streaming flag -s to output the execution of the command in real time.

/aws/mde/mde -s command <command-id>
