dockerClient.containers.create(..., ports={...: None}) does not work in docker client 3.2.0 and upwards

SDK version: 4.4.4
OS: Windows, also reproduced in WSL, and mac
python version: 3.8
reproduced in the following docker versions:

client: 3.2.2, engine: 20.10.5
client: 3.2.1, engine: 20.10.5
client: 3.2.0, engine: 20.10.2

The following code snippet:

client = DockerClient.from_env()
client.images.pull("redis:latest", platform=None)
container = client.containers.create("redis:latest", detach=True, ports={11234: None})
try:
    container.start()
    container.reload()
    portmap = container.attrs["NetworkSettings"]["Ports"]
    print(portmap['11234/tcp'])
finally:
    container.kill('SIGKILL')

prints an empty list [] on docker client versions 3.20 onwards, and a list of host ports/ips for earlier versions.

Hi @bentheiii

First of all, thank you for the code snippet.

The containers documentation explain how ports should be used:

The keys of the dictionary are the ports to bind inside the container, either as an integer or a string in the form port/protocol, where the protocol is either tcp, udp, or sctp.

~~So you have to inform the protocol like {"11234/tcp": None}.~~

I could not reproduce the empty list on Linux, so I suggest you print the portmap variable to be able to see the entire dictionary.

Have a nice day :)

PS: I'm preparing a windows machine to try to reproduce the problem.

Hi and thanks for the quick reply, I can reproduce the problem on multiple machines (windows and mac)

client = DockerClient.from_env()
client.images.pull("redis:latest", platform=None)
container = client.containers.create("redis:latest", detach=True, ports={11234: None})
try:
    container.start()
    container.reload()
    portmap = container.attrs["NetworkSettings"]["Ports"]
    print(portmap)
finally:
    container.kill('SIGKILL')

portmap={'11234/tcp': [], '6379/tcp': None}

Hi @bentheiii

Sorry to ask you again, but the attempt to recover my windows machine was a total failure.

Could you add a print right before reloading the container to be sure that is happening since the container creation?

client = DockerClient.from_env()
client.images.pull("redis:latest", platform=None)
container = client.containers.create("redis:latest", detach=True, ports={11234: None})
try:
    container.start()
+   portmap = container.attrs["NetworkSettings"]["Ports"]
+   print(portmap)
    container.reload()
    portmap = container.attrs["NetworkSettings"]["Ports"]
    print(portmap)
finally:
    container.kill('SIGKILL')

In the meanwhile, I will figure out how to debug that.

Thanks and have a nice day :)

Hello, I have run the following code:

client = DockerClient.from_env()
client.images.pull("redis:latest", platform=None)
container = client.containers.create("redis:latest", detach=True, ports={11234: None})
try:
    print('A', container.attrs)
    container.start()
    print('B', container.attrs)
    container.reload()
    print('C', container.attrs)
finally:
    container.kill('SIGKILL')

this is the result:

filtering only ["NetworkSettings"]["Ports"] evaluates to:

A {}
B {}
C {'11234/tcp': [], '6379/tcp': None}

EDIT: I'm just now noticing the strange behaviour, will investigate further if I have time

It appears that the issue can be fixed by introducing a small delay (even a function call) between the start and reload calls

client = DockerClient.from_env()
container = client.containers.create("redis:latest", detach=True, ports={11234: None})

def report(label):
    attrs = container.attrs
    portmap = attrs["NetworkSettings"]["Ports"]
    print(label, 'all attrs', attrs)
    print(label, 'portmap', portmap)

try:
    report('A')
    container.start()
    container.reload()
    report('B')
    container.reload()
    report('C')
finally:
    container.kill('SIGKILL')

output:

My output (linux) was:

A portmap {}
B portmap {'11234/tcp': [{'HostIp': '0.0.0.0', 'HostPort': '49155'}], '6379/tcp': None}
C portmap {'11234/tcp': [{'HostIp': '0.0.0.0', 'HostPort': '49155'}], '6379/tcp': None}

@ulyssessouza could you try that as well?

Thanks @bentheiii @ulyssessouza

Hi @bentheiii

I´m sorry to ask you again, but could you try to play around with container.reload(timeout=XXXXX)?

Unfortunately, that issue doesn't happen on Linux, and Docker doesn´t work inside a Windows VM.

Thanks again, and have a nice day :)

I think this is a Docker Desktop issue, so this should be in the docker for-mac/for-win repository?
