Use openssl to create an x509 self-signed certificate authority (CA), certificate signing request (CSR), and resulting private key with IP SAN and DNS SAN
# Define where to store the generated certs and metadata.
DIR="$(pwd)/tls"
# Optional: Ensure the target directory exists and is empty.
rm -rf "${DIR}"
mkdir -p "${DIR}"
# Create the openssl configuration file. This is used for both generating
# the certificate as well as for specifying the extensions. It aims in favor
# of automation, so the DN is encoding and not prompted.

JQ to filter JSON by value

JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)
