Permission denied

[yoieh]

Cant get this to work at all:

Im trying to return running containers inside of a container ruing php, apache and this library.

<?
use Docker\Docker;
$docker = new Docker();
$containers = $docker->getContainerManager()->findAll();
?>

[error] [client 10.0.0.15] PHP Fatal error:  Uncaught exception 'Http\\Client\\Exception\\NetworkException' with message 'Permission denied' in /var/www/vendor/php-http/socket-client/src/Client.php:112\nStack trace:\n#0 /var/www/vendor/php-http/socket-client/src/Client.php(80): Http\\Client\\Socket\\Client->createSocket(Object(GuzzleHttp\\Psr7\\Request), 'unix:///var/run...', false)\n#1 /var/www/vendor/php-http/client-common/src/HttpClientDecorator.php(27): Http\\Client\\Socket\\Client->sendRequest(Object(GuzzleHttp\\Psr7\\Request))\n#2 /var/www/vendor/php-http/client-common/src/PluginClient.php(81): Http\\Client\\Common\\EmulatedHttpAsyncClient->sendRequest(Object(GuzzleHttp\\Psr7\\Request))\n#3 /var/www/vendor/php-http/plugins/src/DecoderPlugin.php(67): Http\\Client\\Common\\PluginClient->Http\\Client\\Common\\{closure}(Object(GuzzleHttp\\Psr7\\Request))\n#4 /var/www/vendor/php-http/client-common/src/PluginClient.php(156): Http\\Client\\Plugin\\DecoderPlugin->handleRequest(Object(GuzzleHttp\\Psr7\\Request), Object(Closure), Object(Closure))\n#5 /var/www/vendor/php-http/plugins/src/Content in /var/www/vendor/php-http/socket-client/src/Client.php on line 112

This tells me that is some thing to do with uids or gids.
I have added docker group to the container gid 2000 and www-data has a gid of 33.
On my linux vm the docker groups guid is 2000 and www-data has an gid of 33.

Running ubuntu 16 tls as vm with docker installed and container created with:

sudo docker run -d --restart=always -p 8040:80 --name site -v /var/www/site/:/var/www/ -v /root/_dockerlogs/site/:/var/log/apache2 -v /var/run.docker.sock:/var/run/docker.sock cfd44bc6f9fb

I have now tied to add my user to docker group in VM. I thought docker group should have access to the docker socket but has not and probably my problem.

How do I then solve this problem and use this library?

-v /var/run.docker.sock:/var/run/docker.so"c"k ?

[yoieh]

This was just a typo in the issue

-v /var/run.docker.sock:/var/run/docker.so"c"k ?

Your user inside the container (then the www-data) should be attached to the docker group gid of the host (which is 2000), so you should normally execute this command inside your container :

usermod -aG docker www-data

[yoieh]

This i have already done from inside and outside the docker container.

usermod -aG docker www-data

cat /etc/group
...
docker:x:2000:www-data
...

[CliffLin]

Can you show the info about cat /etc/group | grep docker inside and outside of container

[yoieh]

Its the same sorry i think i found and fixed the issue:

-v /var/run.docker.sock:/var/run/docker.sock

/var/run.docker.sock should be /var/run/docker/sock a mistake from my side.

Thanks for the response!

Glad you find a solution
