<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'><br> Via my experience :<br> 1. eugeneware/docker-wordpress-nginx:latest (RDO Juno on Fedora 21 TwoNode Cluster Controller&&Network and Compute ML2&OVS&VXLAN setup ) may be installed only on Controller. I can install on Compute node ( Nova-Docker driver been built via stable/juno installed on both nodes ) tutum/tomcat, tutum/mysql ubuntu-rastasheep (sshd), but not docker-wordpress-nginx. It just won't come up (two installation pages and it dies). <br> 2. When I log into Ubuntu-Rastasheep installed on Controller I can run `apt-get update`, when I log into the same Ubuntu-Rastasheep been installed on Compute `apt-get update` hangs on waiting for headers. I can ping 8.8.8.8, but TCP/UDP services are locked . Wget doesn't work and etc .. .<br> <br> All this issues got fixed on similar CentOS 7 Cluster after kernel upgrade up to 3.10.0-123.20.1.el7.x86_64. I had same problems on CentOS 7 with kernel 3.10.0-123.13.2.el7.x86_64.<br>The most recent `yum update` upgraded just kernel on CentOS 7.<br><div><br>Thanks.<br>Boris<br></div> </div></body> </html>
