New --private-key-file flag for Meroxa CLI Commands

We have introduced a new flag (--private-key-file) and an improved error message in the meroxa resources create command with the latest Meroxa CLI release v2.18.0.

This new --private-key-file flag is related to the --ssh-private-key flag when setting up a resource with an SSH Tunnel. It is also related to the --password flag when setting up a Snowflake resource. The new --private-key-file flag is present alongside the existing --ssh-private-key and --password flags, but eventually we will deprecate both of those existing flags.

The --private-key-file flag is preferred as it reduces the chance of having a whitespace issue when creating a resource due to shell formatting of the private key value, and it prevents sensitive values from lingering in the shell history.

Using this flag when creating a resource with an SSH Tunnel looks like the following example:

$ meroxa resource create pg_db
    --type postgres \
    --url postgres://$PG_USER:$PG_PASS@$PG_URL:$PG_PORT/$PG_DB \
    --ssh-url ssh://user@[email protected]:22 \
    --private-key-file ~/.ssh/id_ed25519

Using this flag when creating a Snowflake resource looks like the following example:

$ meroxa resource create snowflake \
    --type snowflakedb \
    -u "snowflake://$SNOWFLAKE_URL/meroxa_db/stream_data" \
    --username meroxa_user \
    --private-key-file /Users/me/.ssh/id_rsa

In addition, if there is still somehow a formatting issue with the private key provided, you would have previously seen this error message from this command:

$ meroxa resource create snowflake \
    --type snowflakedb \
    -u "snowflake://$SNOWFLAKE_URL/meroxa_db/stream_data" \
    --username meroxa_user \
    --private-key-file /Users/me/.ssh/id_rsa
Creating "snowflake" resource in "common" environment...
Error: internal error

With all of these changes, we have updated the error message to be more actionable, as in the following example:

$ meroxa resource create snowflake \
    --type snowflakedb \
    -u "snowflake://$SNOWFLAKE_URL/meroxa_db/stream_data" \
    --username meroxa_user \
    --private-key-file /Users/me/.ssh/id_rsa
Creating "snowflake" resource in "common" environment...
Error: the private key provided is not formatted as expected. please review and try again
