How do we change the install location to another drive?
beckerben opened this issue · 7 comments
We are trying to figure out how to install to the "d:" drive rather than the "c:\ProgramData\Docker" and can't figure out how to do this. We tried specifying the DockerPath and DockerDPath parameters but ran into issues with that.
Hey @beckerben, have you tried using --installation-dir=<path>
? This changes the default installation location (C:\Program Files\Docker\Docker)
.

We're installing on a windows server and can't use the docker desktop so are using the install-docker-ce.ps1 script provided in this repo. It doesn't seem to allow us to change the default installation path. We tried hacking it without success.
I see. @brasmith-ms @Howard-Haiyang-Hao is there any limitations to setting DockerPath
and DockerDPath
to "d:" drive?
Hello, it sounds like you would like to switch your "data-root" to a directory on the D: drive. This can be done adding a configuration file for Docker. Here is a doc that shows how to change the data-root among other configurations. The sample json in the example specifies the alternate path for the data (such as images and containers) to be stored:
{
"data-root": "d:\docker"
}
Please note that Docker service needs to be restarted after adding/modifying Docker configurations.
A simple powershell function to do this operation may look like this:
function SetupDocker()
{
$daemonPath = Join-Path $Env:ProgramData "Docker\config\daemon.json"
if (Test-Path $daemonPath)
{
Write-Host "Daemon file exists. Skipping docker set up..."
}
else
{
Write-Host "Changing docker configurations..."
Set-Content -Path $daemonPath -Value '{ "data-root": "D:\\docker" }'
Restart-Service Docker
}
}
@beckerben I was able to get the docker data folder created on a different drive. Here are the steps that I took:
- dockerd --unregister-service
- dockerd --register-service --run-service --data-root e:\docker
- net start docker
Please let me know if this is anything else that I can help with.
To install the docker to a different location, here are the steps:
-
"Docker Desktop Installer.exe" install --accept-license --backend=windows --always-run-service --windows-containers-default-data-root=d:\dockerdata --installation-dir=d:\docker
If you reboot your host, the docker service many stop working again. Here is a workaround that I did:
