A couple of things I ran across today when trying to install Docker on Windows 10 Home.<\/p>\n
All the documentation I have run across so far seems to assume that you have a freshly installed Windows. <\/p>\n
Docker for Windows 10 Home in 2020 is basically Docker for Linux ran through the WSL (Windows Subsystem for Linux) VM. <\/p>\n
WSL seems very nice, though it takes up a fair chunk of disk space. The only caveat I ran into so far as is that you are strongly recommended to use the Linux file system when working on the Linux side, so that side of the set-up is not as transparent as one might have hoped.<\/p>\n
If you previously toyed with or used Docker on Windows, you need to uninstall the old Docker before you can install the new one (even though the new one runs on a different ‘machine’).<\/p>\n
This works just as with any Windows program, so far so good. <\/p>\n
Note 1.<\/strong> The Docker uninstall does not uninstall everything and the things it leaves behind will<\/em> conflict with the new Docker. I kid you not.<\/p>\n The error message you get is something like “could not read CA certificate”.<\/p>\n I had to a) manually remove two sets of environment variables<\/a> and then b) restart Windows. Unlike the winning answer I did not have to uninstall Virtualbox.<\/p>\n Once you have done that, Docker will run just fine. So you start playing with the tutorial, only to find out that:<\/p>\n Note 2.<\/strong> The Docker tutorial binds to localhost.<\/p>\n Which in my case meant I could not see the tutorial, because I had already bound localhost<\/em> on my host machine (Windows) to a XAMPP. <\/p>\n On the Linux VM, localhost<\/em> gets ‘correctly’ bound to the Docker container, so at least that was a relief. (I found out through installing and running the Lynx web browser. I guess I could have used curl<\/em>.)<\/p>\n In the WSL documentation, under Comparing WSL 1 and WSL 2, sub-section Accessing Linux networking apps from Windows (localhost)<\/a>, it is explained how to find out the IP address of the Linux VM (in your VM’s shell enter ‘ip addr’ and use the inet<\/em> value of the eth0<\/em> entry) and you can use that to access your container’s web server from the host system. I don’t know if this address persists across sessions.<\/p>\n Disclaimer: I may have set up things incorrectly, in which case this memo will send the unaware reader googling for help even further into the woods. Certainly that would explain why I haven’t found any documentation on especially the second issue. In that case, please let me know in the comments where I went wrong.<\/p>\n","protected":false},"excerpt":{"rendered":" A couple of things I ran across today when trying to install Docker on Windows 10 Home.
