I am following this guide to install discourse on AWS EC2 instance. Completed all the steps except Elasticache (not using separate Redis). After finishing the discourse setup, I need to edit my app.yml for change in RDS and SMTP settings. But it’s showing that File ‘containers/app.yml’ is unwrita…

There you go. You aren’t logged in as root. And the file belongs to the root user. That’s why you aren’t able to write to that file. Actually, with EC2, you cannot login as root directly. Now, you’re logged in as ubuntu user. type in sudo su -

Have you checked the owner of the app.yml file?

from your command line, cd to the containers folder and type ls -l

Sorry I don’t know much about Unix commands. Can you give me full command that I should enter to find out the owner of the app.yml file?

cd /var/discourse/containers && ls -l then run whoami

Showing this : -rw-r–r-- 1 root root 3819 Jul 30 10:21 app.yml

Okay. Actually initially I followed the commands given here . Just tried this : sudo nano app.yml And now I can make changes!

Thats great. You’ll have to remember to do this everytime you need to make changes on your instance

はい。実は最初は、こちらに記載されたコマンドに従いました。

試しに以下を実行しました：sudo nano app.yml

これで変更が可能になりました！
