Step 6: Update the Cookbook to Add a User
Update your cookbook by adding a recipe that adds a local user to the instance and sets the user's home directory and shell. This is similar to running the Linux adduser or useradd commands or the Windows net user command. You add a local user to an instance, for example, when you want to control access to the instance's files and directories.
You can also manage users without using cookbooks. For more information, see Managing Users.
To update the cookbook on the instance and to run the new recipe
On your local workstation, in the
recipessubdirectory in the
opsworks_cookbook_demodirectory, create a file named
add_user.rbwith the following code (for more information, go to user):
user "Add a user" do home "/home/jdoe" shell "/bin/bash" username "jdoe" end
At the terminal or command prompt, use the tar command create a new version of the
opsworks_cookbook_demo.tar.gzfile, which contains the
opsworks_cookbook_demodirectory and its updated contents.
Upload the updated
opsworks_cookbook_demo.tar.gzfile to your S3 bucket.
Follow the procedures in Step 5: Update the Cookbook on the Instance and Run the Recipe to update the cookbook on the instance and to run the recipe. In the "To run the recipe" procedure, for Recipes to execute, type
To test the recipe
Log in to the instance, if you have not done so already.
From the command prompt, run the following command to confirm that the new user was added:
grep jdoe /etc/passwd
Information similar to the following is displayed about the user, including details such as the user's name, ID number, group ID number, home directory, and shell:
In the next step, you will update the cookbook to create a directory on the instance.
