demo's Issues

Unable to parse config file

Trying to run the installer the python to read the cfg.yml fails because the python script can not include/find the yaml module. Suggest installing pyyaml as part of the installer script.
This can be accomplished with pip install pyyaml, but only if user has python-pip installed. Alternative is to apt-get pyyaml.

Please see output from below:
contiv@contivB1:$ bash net_demo_installer
Parsing config file...
Traceback (most recent call last):
File "./genInventoryFile.py", line 4, in

ImportError: No module named yaml

I have brought the contiv cluster manually due to the OVS issue with ./net_demo_installer.

Errors when not allowing Passwordless Sudo access

  • Install failed because it couldn’t run: "apt-get install python-apt -y -q --force-yes” on half the nodes.
  • Contiv Standalone Install: FAILED! => {"changed": false, "failed": true, "msg": "AnsibleUndefinedVariable: ERROR! 'dict object' has no attribute u'ansible_enp4s0f0'"} on all hosts

Both issues were resolved once I went ahead and implemented in passwordless sudo.

Problems with k8s demo script

Need to add to k8s demo instructions README:
Make sure ifconfig is installed (sudo yum install net-tools)
Names suggested in cluster_defs.json.README (k8master and k8node-XX) are NOT optional (names are hardcoded in verification step).

docker installation is failing

I had run the script and everything was up. My VMs shut down for some reason. Once I brought them up, docker swarm and netmaster were down. I tried running the script again. I am consistently running into this error

TASK [docker : ensure docker is started] ***************************************
fatal: [node1]: FAILED! => {"changed": false, "failed": true, "msg": "Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.\n"}

k8sdemo: Split upgrade and clean_restart

Currently clean_restart.sh is used for upgrade of contiv binaries. clean_restart.sh erases all contiv configuration - networks, epgs etc, and so all kube pods need to be recreated. Will be good to separate out upgrade/clean functionality such that upgrade retains contiv config.

swarm client and server version mismatch

Need help on how to set DOCKER_HOST

At the end of install, the installer needs to provide a note on how the DOCKER_HOST should be set.
The previous installer provided this info and it is necessary for a user who has no idea how the docker cluster is set up by ansible.

Post Install Rules not Applying to Traffic

After a successful install and running netctl to create policy, rules and group. Traffic is not being affected by the rules as expected.
So after running the instructions from docks.contiv.io to try and reproduce the same effect blocking the traffic. It hasn’t been successful as all traffic is passing as normal and ignoring any applied rule.
I believe contiv might have an issue or the instructions have changed for setting up rules.

demo/k8s: setup_k8s_cluster.sh issues

  • setup_k8s_cluster.sh fails due to a lack of wget, bzip2, python-netaddr installed on host
    Manually installing packages on host to get around issues.
  • setup_k8s_cluster.sh fails because contivk8s not found after fetch/extraction
    it appears tar xvfj netplugin-$contivVer.tar.bz2 failes to execute, manually ran the tar command to move on

add aci-gw version variable in net_demo_installer script

In current script, it fetches aci-gw container via ansible playbook with latest tag. Add support to specify version so that we can specify specific aci version in the script and it will pull that container with that tag from docker hub.

demo/k8s: prepare.sh issues

  • msg: Aborting, target uses selinux but python bindings (libselinux-python) aren't installed! recieved on all hosts
    Appears libselinux-python is a requirement for the script, manually installing package on hosts for now.
  • failed: [1-k8master] => {"changed": true, "cmd": "ifconfig "enp4s0f0" "10.199.1.226"/24", "delta": "0:00:00.003001", "end": "2016-03-07 13:59:01.543374", "rc": 127, "start": "2016-03-07 13:59:01.540373", "warnings": []}
    stderr: /bin/sh: ifconfig: command not found
    net-tools isn't a default install anymore with 7, red hat is moving on. Installed manually, to bypass issue for now.
  • Running through the prepare script, I lost connection to installer host on SSH
    it appears the network service needs to be restarted, before connection can be restored
  • Multiple runs of prepare.sh yielded duplicate host entries in hosts file. Suggest a way to clean up hosts file after a failed run.

demo/k8s: VPC Support

Currently any use of VPCs even single legged, can cause the end points to receive mac addresses, but not IPs.

Script not checking version of Ansible

Encountered an issue where the installation fails because an older version of ansible installed. Script should check version and install new if old version is present. Otherwise the following error may occur.

Docker Demo Install Dependency Checks

A few dependencies that should probably be checked for in the Ansible Script:
Install fails due to a lack of python 2 on hosts.
Install fails due to a lack of unzip on hosts.

epel-release repo is also installing ansible 2.1.1.0 now

Reference issue : contiv/ansible#259 and contiv/ansible#264

epel-testing to epel-release repo transition wont work now. ansible 2.1.1.1 version gets installed and then our ansible scripts will fail because of this error :

Duplicate entries in /etc/hosts file after running k8s demo setup

Ran the k8s demo scripts. Noticed there are two entries for netmaster in the /etc/hosts file, one for the node I'm on and one for a different node. I assume the other node had been installed as master for a previous demo.

There are other duplicate entries in the hosts file as well.

k8sdemo: After node reboot, unable to deploy pods

Restart a netplugin k8s node. After restart:
a) netplugin service is not started
b) firewall rules are not saved

After manual restart of netplugin service, below error is seen (possibly due to iptables rules not saved)

k8sdemo: Update documentation

Need to update documentation for k8s setup, listing some items:

  • when/how to run cleanup_machines
  • how to upgrade only k8s

Result of parsed yaml out of order

The result of the parsed yaml file always puts the numerically higher IP address as node 1 instead of the following the order set in the yaml file. For example if the yaml file has ips configured at 74 and 78 as node 1 and 2 respectively the parsed result ends up being 78 and 74 as node 1 and 2 respectively.

k8sdemo: Issues after running cleanup_machines.sh

If you try to setup k8s cluster after running cleanup_machines.sh, below issues are seen:
a) prepare.sh fails saying etcd cannot be uninstalled
b) Setup script fails saying netmaster, netplugin and aci-gw services cannot be started because service does not exist - systemd needs reload after copying the .service files which have been deleted by cleanup_machines.sh
b) docker service is stopped, and not restarted by the setup scripts on master node

net_demo_installer fails due to later OVS version

I am not sure how a later version of OVS got installed on one of the nodes. But even after running net_demo_installer -c/net_demo_installer -r it does not work.
