Use Azure file as docker volumn on Azure linux VM

I have a website running in azure container instance. I noticed that container instance is not cheaper than a linux VM. I would like to migrate to linux VM. 

The process is quite simple.

Firstly, you need to create a linux VM from azure portal. 

Then follow this website to get docker.

https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-docker-ce-1

Most important command is sudo apt-get install docker-ce

Now you have docker installed.  You can run wordpress in docker easily. But I would like to link my new wordpress docker container to my existing azure file.

To do this, we need to install a plugin to allow VM to connect to azure file.

The following steps are from: https://github.com/Azure/azurefile-dockervolumedriver/blob/master/contrib/init/systemd/README.md

//download docker volume driver

wget https://github.com/Azure/azurefile-dockervolumedriver/releases/download/v0.5.1/azurefile-dockervolumedriver

// Move it

sudo mv azurefile-dockervolumedriver /usr/bin/

// make it executable

chmod +x /usr/bin/azurefile-dockervolumedriver

// Download this zip to get the two files

wget https://github.com/Azure/azurefile-dockervolumedriver/archive/v0.5.1.zip

// install unzip

sudo apt install unzip

// unzip the file

unzip v0.5.1.zip

// copy the default file to the right location

sudo cp azurefile-dockervolumedriver-0.5.1/contrib/init/systemd/azurefile-dockervolumedriver.default /etc/default/azurefile-dockervolumedriver

// edit it to match your storage account

sudo vi /etc/default/azurefile-dockervolumedriver

You can get your storage info from azure portal

// Copy service file to right location

sudo cp azurefile-dockervolumedriver-0.5.1/contrib/init/systemd/azurefile-dockervolumedriver.service /etc/systemd/system/azurefile-dockervolumedriver.service

// Start the service, you will need to enter password for following four commands

systemctl daemon-reload

systemctl enable azurefile-dockervolumedriver

systemctl start azurefile-dockervolumedriver

systemctl status azurefile-dockervolumedriver

Use following commands to test, if myvol exist, it will use it, otherwise, a new store created.

sudo docker volume create -d azurefile --name myvol -o share=myvol

sudo docker run -i -t -v myvol:/data busybox

​

// Start a new wordpress instance

sudo docker volume create -d azurefile --name vol -o share=existStorageName

sudo docker run -d --name wp -v vol:/var/www/html -p 80:80 wordpress 

Open http port from azure portal for the VM

​

All good, you can stop your old container instance now, don't forget to update your dns to point to the new server.
