3.2 Perform a volume creation check
To do this, execute:
sudo docker volume ls
Creating volumes is considered successful if the issue of the command contains information about the volumes created:
local cyberway-mongodb-data
local cyberway-nodeos-data
3.3 Start the services
To start a node, it is necessary to start two services — nodeosd and mongo. To simplify the startup process, use the docker-compose utility. Enter the ~/testnet directory (where docker-compose.yml is located), and execute the services load command:
sudo docker-compose up -d
The option -d is used to run the container in the background.
3.4 Check the launch of containers
To check the successful launch of containers, the following cmmand should be executed:
sudo docker ps
Creating containers is considered successful if there are no error messages in the text of the log files and there are messages about creating containers with the names nodeosd and mongo. To analyze the text of log files, you can use the following commands:
The options:
--tail — sets the number of last lines of text;
-f — indicates that it is necessary to monitor the update log file.
The text of the log file nodeosd should also contain information about the generated blocks, as well as about the blocks received from Testnet. The information in the log file about the generated block should have the following form:
The information in the log file about the blocks received over the network should have the following form:
If the testnet is successfully launched, information about blocks received over the network is periodically saved to the log file.
3.5 Recommendation
In case of errors during container launch, it is recommended to stop the functioning of the services, remove Docker volume and create it again.
To stop the functioning of services execute:
To remove Docker volume, use the following command:
To re-create Docker volume, you need to re-execute the instructions, starting with p. 3.1. In case of errors when re-creating Docker volume, you should report this to the CyberWay development team.
