Unable to build the oracle docker image

install_log.txt

I have seen many people's issues got resolved by increasing the docker memory size. I have changed my memory size to 100GB

systemctl stop docker
dockerd --storage-opt dm.basesize=100G
systemctl start docker

but still getting the following error:

/opt/oracle/oraInventory/orainstRoot.sh: No such file or directory (attached the whole installation log)

[root@1efc3c44071a /]# df -B 1G /opt/oracle

df -B 1G / | tail -n 1 | awk '{ print $4 }'
97

Those commands won't permanently change the dm.basesize. If you're actually using device-mapper, my advice is to stop and switch to either btrfs or overlay2 on XFS. Using device-mapper not only gives you storage limitations but is also usually pretty slow.

@Djelibeybi Thanks for your reply. I appreciate your help.

This is in my local. I had a very old desktop and I have installed centos7 and trying to build some docker to practice. Coming back to your comment "Those commands won't permanently change the dm.basesize". I have rebooted the machine and restarted the docker daemon still, I could see the value is set correctly. if it is not permanent why will it show the value 97GB each time? :-)

@gvenzl any suggestions from you :-)

@fremontfancy how are you checking the value? Your commands would set it for the dockerd instance you manually started not the one started by systemd, though in this case, they probably confict. You should rather edit /etc/sysconfig/docker-storage-setup (or equivalent) file on CentOS and make the change there so it's referenced by the systemd startup unit configuration.

Once you've made this change, you'll need to delete and recreate any images as they will have the old value.

It's still recommended not to use device-mapper though. If you installed CentOS 7 just for this, I recommend switching to Oracle Linux 7 instead for a few reasons: first, we create the XFS file system with the right configuration for overlay2 and second, we ship our own supported build of Docker.

@Djelibeybi I mean the host is CentOS7. I am trying to build the oracle docker using Oracle_linux as a base image.

I ran this command from inside the failed docker container. This is my container id : 1efc3c44071a

[root@1efc3c44071a /]# df -B 1G /opt/oracle
Filesystem 1G-blocks Used Available Use% Mounted on
/dev/mapper/docker-253:0-201328928-8c7c3e1e449c3deb01ad940126b0c70d7bc1667cb7215b47033f8969240ba177 100 4 97 4% /

here is the docker-storage content from the host. Do you see any issues with this? :-)
[root@centos7]~# cat /etc/sysconfig/docker-storage
DOCKER_STORAGE_OPTIONS= - -storage-opt dm.basesize=50G
