Add a Host
The first time you start Cello, there will be no hosts in the pool. There are two methods to add more hosts into the pool.
- Through the
Overviewpage: Click the
+button after the
- Through the
Hostspage: Click the
Add Hostbutton at the top right corner.
Then you will see a jumped-out dialog to input the setup info.
Suppose it's a Native Docker server to import as a host, input those fields
- Name: docker_host
- Daemon URL:
192.168.7.220:2375(replace this with your docker host address)
- Capacity: 5
After successful adding, you can find the
docker_host shown in the Host page, with 0 chains and Cap is 5.
Create a Chain
Now we have the free host in the pool, new chains can be create.
Open the Active Chain page, it should be empty now, click the
Add Chain button on the top right corner, input those fields:
- Name: test_chain
And select the host with the
Click the create button to add a new chain with name
test_chain into the pool.
Then you can see it at the Active Chain page.
It will be difficult if you have a numbers of chains to create manually. Cello provides automated ways to save time.
- Use the host action dropdown menu: The Fillup button will fill the host full with chains until its at capacity, while the Clean button will clean all unused chains from the host.
- Use the Autofill checkbox: In the host configuration, you can find a
Autofillcheckbox, which will automatically watch the host and keep it full with chains to the capacity.
Try these methods as you like.
