pyraftlog 1.1.0

Pure Python implementation of the RAFT concencous algorithm

pyraftlog is a RAFT consensus algorithm implementation that provides direct access to the consensus log.

Mock Server

There is a mock server that can be run by calling pyraftlog-mock:

-h, --help              show the help message
-t TYPE, --type TYPE    Type of the node {active,reluctant,passive}
-n NODE, --node NODE   (host:)?port of this node. e.g.: 7001 or localhost:7001
-b NEIGHBOURS, --neighbours NEIGHBOURS  Port(s) of neighbours.
-c COMMAND, --command COMMAND   Port for receiving commands
-l LOG_LEVEL, --log-level LOG_LEVEL Logging level
-f FILE, --file FILE    File to be used as storage (default ./<node_name>.pickle)

Create SSL certs (for mock)

The following set of commands (performed in pyraftlog/certs/) will create a set a CA and device certificate for running the mock cluster on localhost:

# Only do once: generate the root CA key:
> openssl genrsa -out ca.key 4096

# Generate the root CA certificate:
## Country Name (2 letter code) []:GB
## State or Province Name (full name) []:.
## Locality Name (eg, city) []:.
## Organization Name (eg, company) []:.
## Organizational Unit Name (eg, section) []:.
## Common Name (eg, fully qualified host name) []:PyRaftLog
## Email Address []:.
> openssl req -x509 -new -nodes -key ca.key -sha256 -days 1024 -out ca.pem

# Generate device certificates
# Only do once: generate device key:
> openssl genrsa -out localhost.key 4096

# Generate device certificate signing request:
## Country Name (2 letter code) []:GB
## State or Province Name (full name) []:.
## Locality Name (eg, city) []:.
## Organization Name (eg, company) []:.
## Organizational Unit Name (eg, section) []:.
## Common Name (eg, fully qualified host name) []:localhost
## Email Address []:.
> openssl req -new -key localhost.key -out localhost.csr

# Generate a signed device certificate:
> openssl x509 -req -in localhost.csr -CA ca.pem -CAkey ca.key -CAcreateserial -out localhost.crt -days 500 -sha256
