How to change the password for the static credentials used to access the DKP UI

Overview

When DKP is installed, a static user account and credentials are created that can be used to access the DKP Dashboard.   These credentials are displayed using the 'dkp open dashboard' command, or by using the following command:

kubectl -n kommander get secret dkp-credentials -o go-template='Username: {{.data.username|base64decode}}{{ "\n"}}Password: {{.data.password|base64decode}}{{ "\n"}}'

We recommend that you only use these static credentials as a backup to credentials configured using an external identity provider.  However, you may have a need to change the password for these credentials.   

Solution

The following shell script can be used to update the secret that contains the static credentials:

#!/usr/bin/env bash 
set -o errexit 
set -o pipefail 
set -o nounset 

case "$OSTYPE" in 
darwin) 
    new_password=$(head -c45 /dev/urandom | base64 --break=0) 
    ;; 
*) 
    new_password=$(head -c45 /dev/urandom | base64 --wrap=0) 
    ;; 
esac 

kubectl patch \
    --namespace kommander \
    secret/dkp-credentials \
    --type='json' \
    --patch="[ { \"op\" : \"replace\" , \"path\" : \"/data/password\" , \"value\" : \"$new_password\" } ]" 

printf 1>&2 "Password: %s\n" "$new_password"
