Change all '/tmp/kubernetes' occurencies to '/var/agorakube' in all ansible roles.

Today, kube-proxy is set to use 'iptables' mode.
Pls, add the possibility to chose between :

• userspace
• iptables
• ipvs

Set default to 'iptables'

Actually, AgoraKube can't rotate certificates.
Pls add this feature.

• Link summary on README.md file to each part/title of README.md file
• Add a Summary on ./docs/instructions.md and link it to each parts/tiles of ./docs/instructions.md file.

Today, Go is installed by "apt" package manager.
Install it by "wget" to improve installation speed setup.

Add Kubernetes Dashbord as option for deployment

• Role - post-scripts

Is your feature request related to a problem? Please describe.
Today, Agorakube configures Flannel to use the default network interface from the underlying host (The first one).

Describe the solution you'd like
Add possibility to custom, if needed, the interface used by flannel.

This can be done by add after =>

Description

Check the number of components in each hosts group (masters, etcd, workers) in the hosts.yaml.

Masters

If only one master is deployed : display a warning about best practices and HA

If many masters are deployed : check if the number respect K8S best practices here

ETCD

If only one ETCD is deployed : display a warning about best practices and HA

If many ETCD are deployed : check if the number respect ETCD best practices here (section Deployment)

Describe the solution you'd like
Add in the doc an array that explain what params we can use in Agorakube

Additional context
Today, Agorakube doesn't have a clear array that match all possible parameters with their definition and teir possible values (with defaults). Please add this to the docummentation (README.md and docs/instructions.md) to make Agorakube customization easier.

"cfssl" and" cfssljson" tools are installed with a script execution in "agorakube/roles/generate-certs/tasks/install-cfssl-cfssljson.yaml" file.
We sould use Ansible compatible code to install it.

Is your feature request related to a problem? Please describe.
Currently helm is using curl to download and run the helm installer script, this method inside ansible task is not very ansible friendly and its difficult to figure out where the issue is happening. Because its downloading and running the helm installer script in same task.

Describe the solution you'd like
get_url module should be used to download the file and set correct permissions, and then command module can be used to run the installer script.

Describe alternatives you've considered
N/A

Modify Ansible roles to variabilize Kubernetes version to Install.
Actually, only v1.15.0 is supported

add option to install helm

apiextensions-apiserver is not installed wet.

Add the possibility to install this component by default in Agorokube.
https://kubernetes.io/docs/tasks/access-kubernetes-api/configure-aggregation-layer/

apiextensions-apiserver bin is already present in /usr/local/bin/kubernetes/server/bin directory in all masters hosts.

Roles "etcd-gen-init" and "setup-etcd" should be merged for more clarity.

Role "import-certs" must be merged with "setup-etcd/master/worker roles".
This will allow rebooting K8S services if certificates change.

According to the official flannel documentation, make flannel installation more customizable in "post-script" role.
Links:

• https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
• https://github.com/coreos/flannel/blob/master/Documentation/configuration.md

Use variables to customize fileds:

• Network
• SubnetLen
• SubnetMin
• SubnetMax

"Backend" will stay "vxlan" by default for compatibility reasons.

Add upgrade feature for etcd

Replace "ip" vars by "ansible_host" vars across all the code :

• hosts file
• ansible roles (manifests and templates)

This change will allow AgoraKube to deploy K8S components without the "deploy" machine needing to resolv the K8S hosts name through the DNS service.

Linkerd2 need apiextensions-apiserver
Resolve #67 first

Add the possibility to customize the "data_dir" of agorakube (Actually it's /var/agorakube)

Hello

Since Traefik v2.0 has been released, v1.x configuration flags are not supported anymore.
Change the Traefik Image used for Ingress controller (https://github.com/ilkilab/agorakube/blob/master/roles/post-scripts/files/traefik.yaml) to "traefik:1.7" to correct this bug.

Ty :)

Add new logo for AgoraKube Project

Add relevant informations at the end of agorakube execution:
Samples:

• Where find admin kubeconfig
• How to access Kubernetes dashboard

Add possibility to label masters as 'master' and tain them to NoSchedule.
If a host is Master, and Worker at the same time, it must me labeled as 'worker' and 'master', and it must be schedulabe

kubeapps is an open-source software that provide "Application Catalog" for Helm based kubernetes applications.
Add the possibility to install it on Agorakube.

All contributions are welcome :)

All contributors are welcome to this project ! ;)

Here is a non-exhaustive list of contributions needed for this project:

• Documentation
• Add features like new runtime support, new Ingress Controller installation, new CNI plugin, etc...
• Improve the code quality
• ...

It's our first OSS project, so feel free to help us.

Today, all etcd members are configured to persist databases on /var/lib/etcd directory. (See https://github.com/ilkilab/agorakube/blob/master/roles/setup-etcd/templates/etcd.service.j2)

Please, add a variable to customise this directory.

Today, no test lab is provided.

Add instructions about how to test Agorakube in local environment for contributors using Vagrant and VirtualBox

Disable Swap on all Workers.

Add option to install Calico CNI plugin

Hi,

Please, add HA-proxy Support for ingress controller =>https://www.haproxy.com/documentation/hapee/1-9r1/traffic-management/kubernetes-ingress-controller/

Use role "post-scripts"

Today, hostname resolution is done only for Master nodes.
Create a role "populate_etc_hosts" that populate /etc/hosts of all nodes with all hostnames/ip presents in the "agorakube/hosts" file.

Add the possibility to enable/disable this feature with "populate_etc_hosts" variable set to "true/false" in "agorakube/group_vars/all.yaml

Role "server-k8s-gen-configs" should be merged in "setup-master" role for more clarity.

Modify install.sh file to make a conditional installation depending on the OS used.

Modify instructions in order to describe commands for CentOS & RedHat :
https://github.com/ilkilab/agorakube/blob/master/README.md#on-the-k8s-nodes

"gen-encrypt-policy-k8s"role should be merged in "setup-master" for more clarity.

Hello Github Community !

Actually, AgoraKube project only support Ubuntu Bionic (18.04) OS.
We would like to add Centos 7.X support by editing all Ansible Roles.

Your help is welcome ! ;)

Have a nice day :)

Add connexion test between "Ansible Deploy Machine" and "K8S nodes"

This test must be the first task and it must be a breakpoint if one or more nodes are unreachable.

Add Upgrade feature for K8S components :

• kube-apiserver
• kube-controller-manager
• kube-scheduler
• kubelet
• kube-proxy

In the role "generate-certs, add possibility to generate PKI with Openssl instead of CFSSL

Describe the bug
Containerd is getting installed when trying to use docker runtime.

To Reproduce
Steps to reproduce the behavior:

1. Edit group_vars/all.yaml
2. Change runtime to 'docker'
3. Deploy agorakube
4. Containerd will be installed along with docker

Expected behavior
As per kubernetes documentation containerd is not needed for docker runtime.

Is your feature request related to a problem? Please describe.
No compliance checks are done on Hostname values in ansible compliance-checks role.

Describe the solution you'd like
For Agorakube to work, host hostname (seen from command "hostname" on K8S hosts), ansible fact ansible_hostname, and hostname set in agorakube/hosts must be set exactly to the same value.

Add the possibility to configure a proxy for all agorakube components (apt, yum, wget, docker, containerd, kubernetes, ...)

Add option for install kubernetes dashboard user with admin privileges
