Cant connect to Docker on CentOS7 Error starting daemon: error initializing graphdriver: exit status 1


(Maher AlAsfar) #1

i m new to docker

i have gone through multible bloges regarding installing docker on CentOS7 , i m currently running my deployment using VMware virtual machine.

i do have a automated successful deployment via vRealize Automation where i do a yum -y update, disable and stop the firewalld service and install and start the latest docker service 1.9 i think . but it seems the docker daemon isnt running after all that

for example if i do docker pull centos i get the follwoing error :

[root@vRA-VM-123 ~]# docker pull centos
Using default tag: latest
Post http:///var/run/docker.sock/v1.20/images/create?fromImage=centos%3Alatest: read unix /var/run/docker.sock: connection reset by peer.

  • Are you trying to connect to a TLS-enabled daemon without TLS?
  • Is your docker daemon up and running?

[root@vRA-VM-123 ~]# docker daemon
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock)
ERRO[0060] WARNING: No --storage-opt dm.thinpooldev specified, using loopback; this configuration is strongly discouraged for production use
ERRO[0224] [graphdriver] prior storage driver “devicemapper” failed: exit status 1
FATA[0224] Error starting daemon: error initializing graphdriver: exit status 1
[root@vRA-VM-123 ~]#

i was wondering if i m doing anything wrong or missing any steps any help is appreciated

also Here the output for : journalctl -xe for more information

(Maher AlAsfar) #2

the problem resolved by doing the following :

rm -f /etc/sysconfig/docker-storage
echo “DOCKER_STORAGE_OPTIONS= -s overlay” > /etc/sysconfig/docker-storage

it would be greate if someone can explain why
