filter plug-ins for developing ansible using golang can provide some sample code

May.27,2021

after trying, it can be done using python.
what the previous practice filter returns is that the list, of python cannot be used directly as an array. You need to convert it to a string and return it to OK.

reason: insufficient understanding of python data structure

the implementation is as follows:

def to_join_http_port(nodes, hostvars, ansible_default_netname, port):
    """
    INPUT:
        nodes: groups.group_name
        hostsvars: ansible Built-in vars
        ansible_default_netname: ethernet name
        port: program server port
    RETURN:
        string like '"http://10.32.254.7:8081","http://10.32.254.8:8081","http://10.32.254.11:8081"'
    """
    ips = []
    for node in nodes:
        ips.append(hostvars[node][ansible_default_netname]["ipv4"]["address"])
    return ",".join([ '"http://%s:%s"' % (ip, port) for ip in ips ])


class FilterModule(object):
    def filters(self):
        return {
            'http_port_join': to_join_http_port
        }
