cassemd

To start the server and it's daemon process, components in server include:

  • RESTful HTTP
  • Authorize middleware
  • coordinator
  • Cache middleware
  • Watcher to watch containers' changes.
  • Persistence to persist cassem's data.

Get started

Now, you can start the cassemd server as following command:

# @yeqown@gmail.com
# @cassemagent

./cassemagent \
	-c ./configs/cassemadm.example.toml \		# config file path
	--id="2e422fdf" \ 						# nodeID of cassemagent which is unique
	--raft-base="./debugdata/2e422fdf"  \ 	# raft base directory to store
	--http-listen="127.0.0.1:2021" \		# cassemagent restful HTTP address
	--bind="127.0.0.1:3021" \				# address for raft protocol to communicate to each other
	--join=""								# addresses to send join cluster request
./cassemagent \
	-c ./configs/cassemadm.example.toml \
	--id=2e422fdf \
	--raft-base="./debugdata/2e422fdf"  \
	--http-listen="127.0.0.1:2021" \
	--bind="127.0.0.1:3021" \
	--join=""

./cassemagent -c ./configs/cassemadm.example.toml \
	--id=b6a77ac2 \
	--raft-base="./debugdata/b6a77ac2" \
	--http-listen="127.0.0.1:2022" \
	--bind="127.0.0.1:3022" \
	--join="127.0.0.1:2021"

./cassemagent -c ./configs/cassemadm.example.toml \
	--id=a035b428 \
	--raft-base="./debugdata/a035b428" \
	--http-listen="127.0.0.1:2023" \
	--bind="127.0.0.1:3023" \
	--join="127.0.0.1:2022" --join="127.0.0.1:2021"

then you'll get the following content:
