dockerpy

so basically I am trying to run a cassandra docker instance (2.1) and run cqlsh commands following instructions from https://hub.docker.com/_/cassandra/ . $ docker run --name some-cassandra -d cassandra:2.1 $ docker run -it --link some-cassandra:cassandra --rm cassandra sh -c 'exec cqlsh "$CASSANDRA_PORT_9042_TCP_ADDR"' or $ docker run -it --link some-cassandra:cassandra --rm cassandra cqlsh cassandra Manually everything works fine as expected , but when trying to automate this flow with docker-py ,I am having issues with running cqlsh shell. I am not able to execute the cqlsh shell and run

I try to start a docker container with docker-py (Version 1.3.1). I want to map the container internal ports to different ports but fail to expose them properly. I do this like so: def start_container(client, host_config, image_tagged_name, command): print ("create_host_config", host_config.binds, host_config.port_bindings) the_host_config = create_host_config(binds = host_config.binds, port_bindings = host_config.port_bindings); the_ports = host_config.port_bindings.values(); print ("create_container", image_tagged_name, command, the_ports, the_host_config) cont_id = client.create_container

I'm trying to pull docker images from a private repository hosted in Docker hub https://registry.hub.docker.com/u/myname/myapp like this using the docker remote API. The doc is not clear as to how to specify the authentication credentials in a POST request like this curl -XPOST -H "X-Registy-Auth: base64_encoded_authconfig_object" "http://localhost:4243/images/create?fromImage=myname/myapp" This also does not elaborate on how exactly the authconfig is generated. This talks about sending in a base 64 encoded json with a structure like this: { "index_url": { "username": "string", "password":

The aim here is to use a docker container as a secure sandbox to run untrusted python scripts in, but to do so from within python using the docker-py module, and be able to capture the output of that script. I'm running a python script foo.py inside a docker container (it's set as the ENTRYPOINT command in my Dockerfile, so it's executed as soon as the container is run) and am unable to capture the output of that script. When I run the container via the normal CLI using docker run -v /host_dirpath:/cont_dirpath my_image ( host_dirpath is the directory containing foo.py) I get the expected
