Here you can send JSON data over HTTP using curl directly (or similar http client) to port 7980:

$ curl -d '{"test":1,"timestamp":1518086046}' \
localhost:7980/v1/data/testtopic

You can batch JSONs and prozzie will split JSON messages by itself:

$ curl -d \
'{"test":1,"timestamp":1518086046}{"test":2,"timestamp":1518086047}' \
localhost:7980/v1/data/testtopic

You can check that messages are properly delivered using prozzie kafka consume testtopic.

The http2k connector

Please enable the connector using prozzie config setup http2k. It will ask you SSL/TLS related questions, that you could leave blank if you don’t want to use them.

SSL/TLS

Quick SSL/TLS setup

Here you have some instructions if you want to test the http2k TLS implementation quickly. It should be easy to change the individual steps, like obtaining the key/certificate pair or adapt the HTTP client option from curl.

Generate key/certificate pair

To generate a key-certificate pair, you can use the next command. You may need to adapt it depending on your openssl installation:

$ openssl req \
-newkey rsa:2048 -nodes\
-keyout 'key.pem' \
-x509 -days 3650\
-subj "/CN=localhost/"
-extensions SAN \
-config <(cat /etc/ssl/openssl.cnf - <<'EOF'
[req]
distinguished_name = req_distinguished_name

[req_distinguished_name]

[ SAN ]
subjectAltName=DNS:localhost
EOF
) \
-out 'certificate.pem'

Change every parameter at convenience, taking into account:

  • Name of key/certificate produced (-keyout, out)
  • Validity in days (-days)
  • Exported common names and alternative names. Need to match with client requests.
  • openssl.cnf and heredoc (lines between EOF) content.

You need to generate another key/certificate pair if you want to use the client authentication mechanism too.

After that, answer the questions of command prozzie config setup http2k.

Testing with curl

You can make requests using https if you have configured certificate common name or alternate name:

curl -v -d '{"test":1}' https://localhost:7980/v1/data/abc

Or ignore the certificate’s common name with -k option:

curl -k -v -d '{"test":1}' https://localhost:7980/v1/data/abc

If you have set up a client verification CA, you will need to use the generated client key/certificate pair with the --key and --cert options:

curl -k -v -d '{"test":1}' \
--key client-key.pem \
--cert client-certificate.pem \
https://localhost:7980/v1/data/abc

Variables

You can set these variables in the environment before calling prozzie config setup, use them on prozzie config set http2k VAR=VAL, or delete them with prozzie config set http2k VAR=.

ENV Description
HTTP_TLS_KEY_FILE Private key to use (blank for plain http)
HTTP_TLS_CERT_FILE Certificate to export (blank for plain http)
HTTP_TLS_CLIENT_CA_FILE Certificate Authority for clients (blank for no client verification)
HTTP_TLS_KEY_PASSWORD Password to decrypt key (blank for no password)
