Cannot change ownership of host directory mounted about docker-machine-nfs

[NikolayMurha]

@Hippoom try to replace -mapall=<your-uid>:<your-gid> to -maproot=0 in /etc/exports and restart nfsd by sudo nfsd restart. Docker-machine reboot is not necessary.
It works fine for me.

[marvincaspar]

With "-v /var/lib/mysql" it works, with "-v /User/myaccount/mysql-data:/var/lib/mysql", No.

Same problem here. I prefer to link the volume to the hosts, so that the data will not lose if I recreate all containers.

[tonivdv]

Hello @Hippoom ,

So there was already data in your "$(pwd)/data" directory? If yes, did you try with another empty location to see if it worked?

Personally I never use mysql data like this. I always create data containers, as it's faster and less issues with, well permissions :)

[Hippoom]

@tonivdv Thanks for the response.

The "$(pwd)/data" is empty and does not even exist before I run the command.

[Hippoom]

@tonivdv with data containers approach:

$: docker create --name mysqldata -v $(pwd)/data:/var/lib/mysql mysql:5.6 /bin/true
3ab93f92bd8dccc1068680238477bc736f07c8d0b3abc2cd57cdbd5841d384c8
$: docker run -d --volumes-from mysqldata -e MYSQL_ALLOW_EMPTY_PASSWORD=yes mysql:5.6
a5bca62d8ec3b541b03c0509b8de759bfd65f3ad99b8d5d74f5363837bf5ce1d
$: docker logs a5bca62d8ec3b541b03c0509b8de759bfd65f3ad99b8d5d74f5363837bf5ce1d
chown: changing ownership of `/var/lib/mysql/': Operation not permitted

It seems I just cannot bind the host directory....

[tonivdv]

Hello @Hippoom ,

Sorry for the delay, seems I missed the notification (thanks to @MurgaNikolay I got a new one :) )

Can you try again following:

docker create --name mysql-data     -v /var/lib/mysql      mysql:5.6
docker run --name="mysql" --volumes-from mysql-data -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d mysql:5.6

This does work for me:

toni at t-mac in ~/dev/docker  
$ docker create --name mysql-data     -v /var/lib/mysql      mysql:5.6
48449859c4fd7d6a6310d4c9a25aae283a451cfc7cdb8ade8e3067f579c4cdfd

toni at t-mac in ~/dev/docker  
$ docker run --name="mysql" --volumes-from mysql-data -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d mysql:5.6

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/bin/mysqladmin -u root password 'new-password'
  /usr/bin/mysqladmin -u root -h 93ef581fdf77 password 'new-password'

Alternatively you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

[tonivdv]

@Hippoom Were you able to test it again?

[Hippoom]

@tonivdv Hi, sorry for late response.

With "-v /var/lib/mysql" it works, with "-v /User/myaccount/mysql-data:/var/lib/mysql", No.

I'll try @MurgaNikolay 's approach sometime later.

[tonivdv]

@Hippoom If you want to use a data container you should do it the way I do it. There is no need to share your host directory with the guest because it's empty anyway.

Unless you have other requirements, but even then there are ways to access the files through different means.

Just want you to avoid struggling with host/guest permissions when it's not necessary :)

Let us know how it goes with @MurgaNikolay approach.

Cheers

[Hippoom]

@tonivdv

@MurgaNikolay 's solution works fine on my machine. I think it is ok to close the issue.

Sorry for the delay :)

[tonivdv]

Great. Yet another option to make available through the command line. I'll work on that.

[Hippoom]

Just to note:

With @MurgaNikolay solution, the owner of all the files written by docker is root of the host machine.

[NikolayMurha]

Not so quite. This solution map root on guest machine to root on host machine only.
This allow chown and chmod commands by nfs. But files/folders uids stay as is, and uids existed on guest machine can't be missing on host. So, for example, if you create file in docker machine (DM) by user ubuntu with UID 999, this file will be created on host machine with UID 999.
If file on DM will created by root, he will be created by root on host machine too.
-mapall option map all UIDs/GIDs on DM to your local user on host machine, and root user too.
