DOCKERINFO

Easily extract information from docker containers

Since version 1.2 can extract containers logs.

Example:

from dockerinfo.docker_info import DockerContainerInfo, DockerHelper

# Create an instance of the DockerHelper class and list the existing containers.
# Use all_containers=True/False to list inactive containers.
docker_info = DockerHelper()
container_list = docker_info.list_containers(all_containers=True)

# Iterate through all found containers and extract information.
print(">>> ITERATING THROUGH ALL EXISTING CONTAINERS AND EXTRACTING INFORMATION")
for container in container_list:
    container_info = DockerContainerInfo(container)
    print(f"Container ID: {container_info.id}")
    print(f"Container Name: {container_info.name}")
    print(f"Container Status: {container_info.status}")
    print(f"Container Log (last 5 lines):")
    for log_line in container_info.get_logs_tail(5):
        print(log_line)

# Extract information from a specific container (in this case, 'test01').
print("
>>> LOOKING FOR A SPECIFIC CONTAINER (test01)")
container = docker_info.get_container_by_name('test01')

if container:
    # If the container is found, create an instance of the DockerContainerInfo class.
    container_info = DockerContainerInfo(container)
    
    # Print container information.
    print(f"Container ID: {container_info.id}")
    print(f"Container Name: {container_info.name}")
    print(f"Container Status: {container_info.status}")

    # Test other methods of the DockerContainerInfo class as needed.
    print(f"Networks (all): {container_info.networks}")
    
    network_name = 'bridge'  # Change the network name as needed.
    network_info = container_info.get_network_config(network_name)
    print(f"Network Info for {network_name}: {network_info}")

    ip_address = container_info.get_network_attribute(network_name, 'IPAddress')
    mac_address = container_info.get_network_attribute(network_name, 'MacAddress')
    print(f"IP Address: {ip_address}, Mac Address: {mac_address}")

    # Print more container information as needed.
else:
    print("Container not found: test01")

Available options:

• id

Returns the container ID.

• name

Returns the container name.

• status

Returns the current status of the container.

• config

Returns the entire configuration of the container.

• hostname

Returns the container's hostname.

• domainname

Returns the container's domain name.

• stopsignal

Returns the stop signal of the container.

• networks

Returns the configuration of all networks of the container.

• get_network_config(network)

Returns the configuration of a specific network of the container.

• get_network_attribute(network, attribute)

Returns a specific attribute of a network of the container.

• mounted_volumes

Returns the configuration of volumes mounted in the container.

• get_logs Get the logs of the container, split into lines. Return a list containing each line of the container's logs as a string.

• get_logs_since(timestamp) Get the logs of the container since a specified timestamp, split into lines.

Args:

timestamp (int): The Unix timestamp from which to start fetching logs.

Return a list containing each line of the container's logs as a string.

• get_logs_since_date(date_string) Get the logs of the Docker container since a specified date.

Args: date_string: A string representing the date in MM/DD/YYYY format.

Returns the logs since the specified date.

Example:

logs_since_date = instance.get_logs_since_date("01/15/2023")

Note: The date string must be in the correct format to avoid conversion errors

• get_logs_tail(lines)

Get the last N lines of the container's logs, split into lines.

Args:

lines (int): The number of lines to retrieve from the end of the logs.

Returns:

Returns a list containing each line of the container's logs as a string.
