The ungleich etcd infrastructure¶

Hey there fellow open/free infrastructure lover, this is a documentation of the ongoing etcd deployment.

1 create ca.crt with openssl
openssl genrsa -out rootCA.key 4096

2 self-sign this certificate.
openssl req -x509 -new -nodes -key rootCA.key -sha512 -days 1024 -out rootCA.pem

3 create a private key for device 1
openssl genrsa -out etcd1.key 2048

4 signing request
openssl req -new -key etcd1.key -out etcd1.csr

5 signing device 1 key
openssl x509 -req -in etcd1.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out etcd1.crt -days 1024 -sha512

6 copy keys scp

7 start test
etcd --name infra0 --data-dir infra0 \
--cert-file=/root/keys/etcd1.crt --key-file=/root/keys/etcd1.key \
--advertise-client-urls=https://[2a0a:e5c0:0:2:0:b3ff:fe39:798b]:2379 --listen-client-urls=https://[2a0a:e5c0:0:2:0:b3ff:fe39:798b]:2379
