Unseal a sealed unit (Machine)ΒΆ

In the circumstance that a OpenBao unit restarts, you will have to manually unseal it. This guide walks you through the necessary steps:

Starting from a cluster where one unit is sealed:

$ juju status
Model  Controller           Cloud/Region         Version  SLA          Timestamp
demo   localhost-localhost  localhost/localhost  3.6.28    unsupported  12:34:35-04:00

App    Version  Status   Scale  Charm  Channel    Rev  Exposed  Message
openbao           blocked      3  openbao  latest/edge  2   no       Waiting for OpenBao to be unsealed

Unit      Workload  Agent  Machine  Public address  Ports  Message
openbao/0*  active    idle   0        10.191.126.116         
openbao/1   active    idle   1        10.191.126.151         
openbao/2   blocked   idle   2        10.191.126.90          Waiting for OpenBao to be unsealed

Machine  State    Address         Inst id        Base          AZ  Message
0        started  10.191.126.116  juju-b8368f-0  ubuntu@26.04      Running
1        started  10.191.126.151  juju-b8368f-1  ubuntu@26.04      Running
2        started  10.191.126.90   juju-b8368f-2  ubuntu@26.04      Running

Set the BAO_ADDR variable to the sealed unit:

export BAO_ADDR=https://$(juju status openbao/2 --format=yaml | awk '/public-address/ { print $2 }' |head -n 1):8200; echo $BAO_ADDR

Unseal the the unit using the same unseal keys as received during the initialization of the OpenBao leader:

bao operator unseal EJoB62t286mjUpSQYZg3mOla3lz/bbElVL5OLnj+rpE=

The units will go back to the active/idle state:

$ juju status
