Phase 1: manual slaves setup Phase 2: play ansible with make

Phase 1: Manual Slaves Setup

We can provide IP addresses in inventories/slaves/static or provide MACs addresses in data/macs/slaves for dynamic IP lookup.

Hardcode data/macs/slaves

Hardcode data in data/macs/slaves with MAC addresses taken from ifconfig -> ether for each slave.

For example from

eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.8.156  netmask 255.255.255.0  broadcast 192.168.8.255
        inet6 fdec:8914:9e28:7a00:55:3465:63aa:a092  prefixlen 64  scopeid 0x0<global>
        inet6 fe80::43e5:d5e:703f:5bb4  prefixlen 64  scopeid 0x20<link>
        inet6 fdec:8914:9e28:7a00:781b:5619:75cd:ee65  prefixlen 64  scopeid 0x0<global>
        ether 88:88:88:88:87:88  txqueuelen 1000  (Ethernet)
        RX packets 492603  bytes 412910119 (412.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 396109  bytes 108760332 (108.7 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 16  memory 0xb3200000-b3220000  

we take ether value 88:88:88:88:87:88 and put it as

88:88:88:88:87:88

In case of multiple interfaces in one slave ie. eno0, eno1, eno2 we put MACs in same line

88:88:88:88:87:88 88:88:88:88:87:89 88:88:88:88:87:90

In case of multiple interfaces in 2 slaves we put MACs in same line for each slave

88:88:88:88:87:88 88:88:88:88:87:89 88:88:88:88:87:90
02:42:79:be:40:4b 02:42:79:be:40:4b

Phase 2: play

make all

It will setup, check and play cluster.

make setup

It will install ansible, valut and encrypt vauly.ymls

make check

Play dryrun for cluster

make cluster

Play for all groups

make master

Play for master group

make slaves

Play for slaves group
