Option to output identity in plain text or json for automation purposes

[avoidik]

What is the problem you want to solve?

There's no way to output generated identity without annotations. The most cleanest solution I've found is this:

MINIO_IDENTITY="$(kes identity of client.crt | tail -n 1 | tr -d '[:blank:]')"

How do you want to solve it?

MINIO_IDENTITY="$(kes identity of client.crt --plain)"

or

MINIO_IDENTITY="$(kes identity of client.crt --json | jq -r '.identity')"

Additional context

1. Are there alternative solutions?

Piping output

2. Would your solution cause a major breaking API change?

No

3. Anything else that is important?

This creates unnecessary complexity for automation

Hey @avoidik, could you please share how you are using kes identity of command ?

the working of kes identity of is, when it is run over terminal, a long version is printed, else just identity is printed.

here is an example

1. here is the output when run in terminal

toastsandwich:~/kes-server> SAMPLE=$(kes identity of client.crt)
toastsandwich:~/kes-server> echo $SAMPLE
Identity: <identity value>

2. here is the output when we create a sh file and we source it
   script.sh

      export TEST=$(kes identity of client.crt)

toastsandwich:~/kes-server> env | grep TEST
TEST=<identity value>

Sure, here is an example:

Save it as kes.sh, and run it

#!/bin/bash

if [[ -z "$IN_DOCKER" ]]; then

docker run --rm -i -t \
    --name kes \
    -v $PWD:/workdir \
    -e IN_DOCKER=1 \
    -w /workdir \
    --entrypoint '/workdir/kes.sh' \
    minio/kes \
    bash

    exit

fi

ln -fsn /kes /usr/local/bin/kes

kes identity new --ip '127.0.0.1' --dns 'localhost' --key server.key --cert server.crt --force "$HOSTNAME"

kes identity new --key client.key --cert client.crt --force minio

echo "Hahaha"

echo $(kes identity of client.crt)

echo "Hahaha"

MINIO_IDENTITY="$(kes identity of client.crt | tail -n 1 | tr -d '[:blank:]')"

cat << EOF > config.yml

      - $MINIO_IDENTITY

keystore:
  fs:

# kes server --config config.yml

At the end:

Hahaha

Hahaha

The reason for this behavior is that KES checks if either, the stdout or the stderr is a terminal.
There are multiple ways to only print the identity value. For example, export MINIO_IDENTITY=$(kes identity of <cert>) or you redirect stdout and stderr.

We can also change the behavior when detecting a terminal to check whether stdout and stderr are terminals.
This does not justify an additional flag
