I think this used to work up to a few months ago. The regular commandline docker:
>> docker run --name 'mycontainer' -d -v '/new' ubuntu /bin/bash -c 'touch /new/hello.txt'
>> docker run --volumes-from mycontainer ubuntu /bin/bash -c 'ls new'
>> hello.txt
works as expected but I cannot get this to work in docker-py:
from docker import Client #docker-py
import time
docker = Client(base_url='unix://var/run/docker.sock')
response1 = docker.create_container('ubuntu', detach=True, volumes=['/new'],
command="/bin/bash -c 'touch /new/hello.txt'", name='mycontainer2')
docker.start(response1['Id'])
time.sleep(1)
response = docker.create_container('ubuntu',
command="/bin/bash -c 'ls new'",
volumes_from='mycontainer2')
docker.start(response['Id'])
time.sleep(1)
print(docker.logs(response['Id']))
..always tells me that new doesn't exist. How is volumes-from
supposed to be done with docker-py?
Below is the current working way to do volume bindings:
volumes= ['/host_location']
volume_bindings = {
'/host_location': {
'bind': '/container_location',
'mode': 'rw',
},
}
host_config = client.create_host_config(
binds=volume_bindings
)
container = client.create_container(
image='josepainumkal/vwadaptor:jose_toolUI',
name=container_name,
volumes=volumes,
host_config=host_config,
)
response = client.start(container=container.get('Id'))
The original answer has been deprecated in the api and no longer works. Here is how you would do it by using the create host config commands
import docker
client = docker.from_env()
container = client.create_container(
image='ubuntu',
stdin_open=True,
tty=True,
command='/bin/sh',
volumes=['/mnt/vol1', '/mnt/vol2'],
host_config=client.create_host_config(binds={
'/tmp': {
'bind': '/mnt/vol2',
'mode': 'rw',
},
'/etc': {
'bind': '/mnt/vol1',
'mode': 'ro',
}
})
)
client.start(container)
