OKD 3.11 ALL IN ONE (un nodo )

1)

verificar que esté correcto el /etc/hostname

[root@qqmelo1c cloud_user]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
# Cloud Server Hostname mapping
172.31.115.132   qqmelo1c.mylabserver.com qqmelo1c master

2) generar las claves ssh key

[root@qqmelo1c cloud_user]# ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /root/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

SHA256:MH3+KnjMDzjolWsaJ60wtHltYlMedGpMtBn7lkqIcz0 root@qqmelo1c.mylabserver.com

The key's randomart image is:

+---[RSA 2048]----+

|      o          |

|     . *         |

|      O o .      |

|   . * * +       |

|  + o E S .      |

| . = O B   .     |

|  = O %+.   .    |

|   * Xoo=. .     |

|    +o.. oo      |

+----[SHA256]-----+

ahora vamos a hacer el copy para que ansible pueda correr en el nodo

[root@qqmelo1c cloud_user]# ssh-copy-id master

/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"

/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys

root@master's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'master'"

and check to make sure that only the key(s) you wanted were added.

una vez que está esto, tenemos que instalar los packages.

yum -y install centos-release-openshift-origin311 epel-release docker git pyOpenSS systemctl start docker systemctl enable docker yum -y install openshift-ansible

Y lueego de esto, lo que falta, es tocar el archivo /etc/ansible/hosts

[OSEv3:children] masters nodes etcd [OSEv3:vars] ansible_ssh_user=root ansible_become=true openshift_deployment_type=origin openshift_master_identity_providers=[{'name': 'htpasswd_auth', 'login': 'true', 'challenge': 'true', 'kind': 'HTPasswdPasswordIdentityProvider'}] openshift_master_htpasswd_users={'admin':'$apr1$qEufOSTX$R1ObTWs7YVwmKSjmaWzCa0', 'developer': '$apr1$ojtj8hHs$C9UZtdLoDs2Hcdw2msKOm0'} os_sdn_network_plugin_name='redhat/openshift-ovs-multitenant' openshift_master_default_subdomain=apps.mylabserver.com openshift_docker_insecure_registries=172.30.0.0/16 openshift_disable_check=disk_availability,docker_storage,memory_availability,docker_image_availability [masters] qqmelo1c.mylabserver.com openshift_schedulable=true containerized=false [etcd] qqmelo1c.mylabserver.com [nodes] qqmelo1c.mylabserver.com openshift_node_group_name='node-config-all-in-one'

Luego, corremos el playbook de los prerequisitos.

ansible-playbook /usr/share/ansible/openshift-ansible/playbooks/prerequisites.yml

Y luego el playbook de la instalación

ansible-playbook /usr/share/ansible/openshift-ansible/playbooks/deploy_cluster.yml
