Docker and kubernetes integration library

Project description

Shiphelm

Table of Contents

Shiphelm is a Python library for interacting with containers more easily. With Shiphelm, you can:

  • Get a list of all running containers
  • Get usage statistics and used ports for a given container by ID
  • Search containers by name or ID
  • Change the open ports of a container
  • Run new containers
  • Work with Docker, and Kubernetes
  • Use Kubernetes clusters and Docker Swarm
  • work on clusters, and swarms of container hosts

Installation

You can install Shiphelm using pip:

pip install shiphelm

PyPI: https://pypi.org/project/Shiphelm/

GitHub Releases https://github.com/Gameplex-Software/ShipHelm/releases

Docker usage example

This code will allow you to manage the local container engine

Standalone Docker installation

from shiphelm.helm import helm

hd = helm() # create an instance of helm

helm.set_engine_manual("docker")

Remote standalone Docker installation

This code will allow you to manage any compatible remote container engine

from shiphelm.helm import helm

hd = helm.reomte_connect('tcp://remote-docker-host:2375') # create an instance of helmdocker for romote management

Remote Docker swarm installation

from shiphelm.helm import helm

hd = helm.helm() # create an instance of helm

helm.set_engine_manual(engine_select="docker", remoteAddress="YOUR ADDRESS HERE", remoteSecurity=<True|False>)

Get a List of Running Containers

running_containers = hd.get_running_containers()

Get a running container by ID

get_container_by_id(container_id)

Get Stats and Ports for a Container by ID

container_stats = hd.get_container_stats(container_id)
container_ports = hd.get_container_ports(container_id)

Search for Containers by Name

containers_by_name = hd.search_containers(name)

Change the Ports of a Container

hd.change_container_ports(container_id, ports)

Rename a Container

hd.rename_container(container_id, new_name)

Add and Remove Containers from Networks

hd.add_container_to_network(container_id, network_name)
hd.remove_container_from_network(container_id, network_name)

Create and Delete Networks

hd.create_network(network_name)
hd.delete_network(network_name)

Run a New Container

container = hd.run_container(
    image=image,
    command=command,
    detach=detach,
    ports=ports,
    environment=environment,
    volumes=volumes
)

Get and Set Environment Variables for a Container

container_environment = hd.get_container_environment(container_id)
hd.set_container_environment(container_id, environment)

Get and Set Volumes for a Container

container_volumes = hd.get_container_volumes(container_id)
hd.set_container_volumes(container_id, volumes)

Example code

This example runs 4 instances of the Docker "Getting Started" container

from shiphelm.helmdocker import helmdocker

hd = helmdocker() # create an instance of helmdocker
container_list = hd.get_running_containers() # call the method on the instance
print(container_list)
w=0

print("Preparing new server...")
while w<3:
    hd.run_container(image="docker/getting-started", detach=1)
    w=w+1

print("Your server is up and ready for connection!")

Kubernetes (K8S) usage example

This code will allow you to manage the local container engine

from shiphelm.helm import helm

hd = helm.helm() # create an instance of helm

helm.set_engine_manual("kubernetes")

This code will allow you to manage any compatible remote container engine

from shiphelm.helm import helm

hd = helm.reomte_connect('tcp://remote--host:2375') # create an instance of helm for romote management

Get a List of Running Containers

running_containers = hd.get_running_containers()

Get Stats and Ports for a Container by ID

container_stats = hd.get_container_stats(container_id)
container_ports = hd.get_container_ports(container_id)

Search for Containers by Name

containers_by_name = hd.search_containers(name)

Change the Ports of a Container

hd.change_container_ports(container_id, ports)

Rename a Container

hd.rename_container(container_id, new_name)

Add and Remove Containers from Networks

hd.add_container_to_network(container_id, network_name)
hd.remove_container_from_network(container_id, network_name)

Create and Delete Networks

hd.create_network(network_name)
hd.delete_network(network_name)

Run a New Container

container = hd.run_container(
    image=image,
    command=command,
    detach=detach,
    ports=ports,
    environment=environment,
    volumes=volumes
)

Get and Set Environment Variables for a Container

container_environment = hd.get_container_environment(container_id)
hd.set_container_environment(container_id, environment)

Get and Set Volumes for a Container

container_volumes = hd.get_container_volumes(container_id)
hd.set_container_volumes(container_id, volumes)

Example code

This example runs 4 instances of the "Getting Started" container

from shiphelm.helm import helm

hd = helm() # create an instance of helm
container_list = hd.get_running_containers() # call the method on the instance
print(container_list)
w=0

print("Preparing new server...")
while w<3:
    hd.run_container(image="ollyw123/helloworld", detach=1)
    w=w+1

print("Your server is up and ready for connection!")

Dynamic engine selection

You may have noticed that the syntax for controling both Docker and Kubernetes are identical, the way the code you write for ShipHelm is run depends on the engine you selected last.

In the last example we used the follwing code to initilise ShipHelm, create an alias, and select a container engine:

from shiphelm.helm import helm

hd = helm.helm() # create an instance of helm

helm.set_engine_manual("kubernetes")

f you want your cod to be able to use either engine that it detects locally you can use the following code instead:

from shiphelm.helm import helm

hd = helm.helm() # create an instance of helm

helm.set_engine_auto()

Remote engines via GUI

To use remote engines you can use the following the examples above to connect programatically or use the below code to open a GUI configuration wizard:

from shiphelm.helm import helm

hd = helm.helm() # create an instance of helm

helm.remote_popup()
