What does Cello do?

Cello is towards the operation system for blockchain networks. It will help user startup, operate and manage the distributed ledgers through dashboards. Using cello, it is always easy to create a blockchain service platform, e.g., BaaS.

Is it possible to manage blockchains across multiple hosts using cello?

Yes, currently, cello supports multiple kinds of agents to utilize various infrastructures.

E.g., with the ansible agent, it's easy to allow cello to manage blockchain networks on multi-servers/vms.

Besides, we are designing the k8s agent now to enable cello employing kubernetes cluster better to host blockchain networks.

How to find the service log in Cello

Run `make log` in the master node.

Make sure the relative ports are not baned by the security group.

Worker node setup failed caused by nfs mount error

Please check the worker node setup output, if has error like this:

     mount: wrong fs type, bad option, bad superblock on 192.168.1.49:
         missing codepage or helper program, or other error
         (for several filesystems (e.g. nfs, cifs) you might
         need a /sbin/mount.<type> helper program)
         In some cases useful info is found in syslog - try
         dmesg | tail or so.

this mean you missing nfs-common packge, run command “apt-get install nfs-common” to install it, and then setup worker node again.

Can not login in localhost:8080 or localhost:8081

With using docker-17.03.0 may cause this problem, Try to use the newer version like docker-17.06.0.

I still cannot resolve my problem

Clean you environment and try to re-clone the latest code.

If still not work, then feel free to open a jira issue to include:

  1. Code Version;
  2. OS type and docker/k8s version;
  3. Logs of the cello services;
  4. Steps to repeat the issue.

Then post the jira link to rocket channel.
