App service time zone does not change it.

Clark 1

Hi.

I have some problems about setting timezone.

My app service is running on Linux service plan. I have tired many ways to change timezone.

I got some information from community.

and I tried those things.

app setting

WEBSITE_TIME_ZONE = Korea Standard Time -> does not work, I guess it is for Windows app service plan.

TZ = Asia/Seoul -> does not work, I guess it is for Linux but...

Does anyone fix timezone issue?

Thank you for answering!

@Clark To open a direct SSH session with your container, your app should be up and running. Have you tried restarting your application and then opening an SSH session?

@Clark Thanks for the response. Could you please confirm the SKU/tier and the runtime stack that your app is running on? Is this a custom container? If yes, you will have to enable SSH via the Dockerfile of your app. You can also verify the logs at: https://<your-app-name>.scm.azurewebsites.net/api/logs/docker

@Clark Sure, thank you. Please refer to the following docs to follow along the detailed configuration steps:

Open an SSH session to a Linux container in Azure App Service

Configure a custom container for Azure App Service - Enable SSH

Most importantly, please ensure that:

you have the necessary configuration for installing the SSH server as part of your app's Dockerfile.

you have the sshd_config file with the correct content added to your image repo and it is copied to the /etc/ssh/ directory.

port 2222 is exposed on the container.

the start-up script for your container starts the SSH server.

@Clarke-1834 After having all of the above in place, you should be able to SSH into your WebApp by browsing to:

https://<app-name>.scm.azurewebsites.net/webssh/host,

authenticate and access the in-browser shell to run commands inside your container.

Running service --status-all should show ssh as one of the services running on the container.

Please reach out if you see issues. Happy weekend! :)

My team is still stuck in a this issue. @BhargaviAnnadevara-MSFT

My project is in Azure DevOps Repo.

We are set Dockerfile and sshd_config.

and this one has a problem.

We tried it dockerfile and Azure Powershell.

it does not work.

Moreover, Does Azure have same solution like this in Azure Portal?

A lot of time we are confused Azure portal way or Azure CLI way.

it is difficult for using compare than AWS...

@Clark Thanks for the additional details.

To fix this error with sshd: sshd: no hostkeys available --exiting,

please add another instruction to generate the host keys:

RUN /usr/bin/ssh-keygen -A

in your Dockerfile just before starting the ssh service.

You can further go through the instructions with the Node.js 10.14 repository to see how it's enabled there. Here is a sample Dockerfile and ssh_setup.sh configuration for your reference.

@Clark Yes, it is true that Timezone for Linux Apps is managed via the TZ application setting. Here is a detailed blog post for your reference.

Here is the setting on my App Service that works well:

Once I saved the setting, my application restarted. Opening an SSH session, I could verify that the Timezone changes did reflect indeed:

You can verify the same by executing the date command in your app's SSH console.
