Thread starter 2xakvT Start date 3. Currently reading. Hey everybody Does anybody installed a matrix snapyse docker container on his system? And get it perfectly running with the external database? Right now I got it running with the internal database. But this is sadly no perfect solution. Happy new year and thanks in advance! Rusty Moderator. NAS Support. What image are you using? For now the offical one. If this doesn't help, you can still modify the generated config file.

The expected structure looks like this: Code:. Indeed the variables are used. I created a docker-compose. Thanks for the answer! Though, I am totaly unclear about HOW matrix is ment to be used, for instance how users are added.With more thanusers, Portainer has become the defacto industry standard for managing Docker and Docker Swarm environments. Docker is a great development tool, and by using it developers can embrace cloud native, applications.

How can you still obtain the benefits of containers, whilst working within their constraints? Portainer is a fully featured management tool for Docker.

It runs locally, giving developers a rich UI to build and publish container images, deploy and manage applications and leverage data persistence and horizontal scaling for their applications. And, o nce an application is deployed into a container, Portainer makes it easy for users to secure, monitor and measure the performance of the platform. The tool negates the need for developers to learn Infrastructure as Code and makes it easy for them to maximize their efficiency which means both users and organizations love it.

The Portainer experience you get when managing a cluster of nodes with Docker Swarm is very similar to the one you get with standalone Docker, which makes the transition easy. Portainer does the hard work of translating the described end state into the Swarm-aware construct and then instructing Swarm to deploy it. If an application fails, Portainer will let you quickly identify why and remediate the issue, and you can even choose to redeploy the application whist preserving all your settings.

Portainer Business includes numerous advanced functionality suitable for Docker-based business environments. RBAC functionalitywhich is lacking in native Docker Swarm systems, allows you to assign your users or their team a specific role, and then apply that role to a cluster.

Portainer does the heavily lifting of ensuring role compliance, thereby turning the insecure Docker Swarm environment into a secure one. With Portainer, you can selectively elevate or decrease a user's effective role through role overrides, providing fine grained access to your entire Docker estate.

Our goal is to make containers accessible to everyone by removing complexity though a simple to use GUI that does the heavy lifting for you.

These virtual machines make it possible to distribute executable environments with all of the dependencies that can easily be run by others. These Docker images can then be stored and distributed on a Docker registry, a collection of these images.

There are a number of open registries on the web, and Synapse hosts a private registry, freely available to our users, which will allow users to create software on a per project basis which can be easily shared across Synapse.

Learn more about Docker and Docker registry. Synapse users interact with the Synapse Docker registry using the standard Docker client. As with Files and Tables, repositories are organized by project and inherit the access permissions from the parent project.

Local Sharing Settings can be applied directly to the repository if permissions should differ from the project.

To learn more about working with Docker using one of our programmatic clients, including code examples for the below tasks, see:. Users can choose to either modify an existing Docker image or build a Docker image from a Dockerfile. You can also choose to not tag your image with an explicit tag, which will by default tag it with latest. Build your own image from a Dockerfile When building a Docker image from a Dockerfile, add a -t to the docker build command with the correct Synapse Docker registry tag.

Learn more about building docker images. To store Docker images, use the docker push command. To push to the Synapse Docker registry, users must be logged into the registry, be a Synapse certified user and have edit permissions:. Note: There is a GB limit per repository image layer.

Note: An alternate way to log in, rather than using a user name and password, is with an OAuth access token. This is unusual when using the Docker command line client, but may occur when using a Docker client within a system that authenticates using the OAuth protocol. To perform docker pull operations the OAuth token must have download scope. To perform docker push operations the token must have download and modify scopes. To access the Docker images stored in Synapse, use the docker pull command.The portability and reproducibility of a containerized process mean we have an opportunity to move and scale our containerized applications across clouds and datacenters.

Containers effectively guarantee that those applications run the same way anywhere, allowing us to quickly and easily take advantage of all these environments. Tools to manage, scale, and maintain containerized applications are called orchestratorsand the most common examples of these are Kubernetes and Docker Swarm.

Before the inception of Docker, developers predominantly relied on virtual machines. But unfortunately, virtual machines lost their popularity as it was proven to be less efficient. Docker was later introduced and it replaced VMs by allowing developers to solve their issues efficiently and effectively. Before getting started with what Docker Swarm is, we need to first understand what Docker is as a platform.

Docker is a tool used to automate the deployment of an application as a lightweight container so that the application can work efficiently in different environments. Docker container is a lightweight software package that consists of the dependencies code, frameworks, libraries, etc. We can use Docker Swarm to make Docker work across multiple nodes, allowing them to share containers with each other.

It's an environment where you can have various Docker images running on the same host operating system. Now, that we have understood what Docker and Docker containers are, let us next look into what Docker swarm is. Docker Swarm is an orchestration management tool that runs on Docker applications.

It helps end-users in creating and deploying a cluster of Docker nodes. Each container within the Swarm can be deployed and accessed by nodes of the same cluster. Docker Swarm can reschedule containers on node failures. Swarm node has a backup folder which we can use to restore the data onto a new Swarm.

What is Docker Swarm: Features and Working

In Swarm, containers are launched using services. A service is a group of containers of the same image that enables the scaling of applications. Before you can deploy a service in Docker Swarm, you must have at least one node deployed. There are two types of nodes in Docker Swarm:. The manager node knows the status of the worker nodes in a cluster, and the worker nodes accept tasks sent from the manager node.

Every worker node has an agent that reports on the state of the node's tasks to the manager. This way, the manager node can maintain the desired state of the cluster. In Docker Swarm, services can be deployed and accessed by any node of the same cluster. While creating a service, you'll have to specify which container image you're going to use.

You can set up commands and services to be either global or replicated: a global service will run on every Swarm node, and on a replicated service, the manager node distributes tasks to worker nodes. Now a question may arise: don't task and service refer to the same thing?

The answer is no.

synapse docker swarm

A service is a description of a task or the state, whereas the actual task is the work that needs to be done. Docker enables a user to create services that can start tasks. When you assign a task to a node, it can't be assigned to another node. It is possible to have multiple manager nodes within a Docker Swarm environment, but there will be only one primary manager node that gets elected by other manager nodes. A service is created based on the command-line interface.

The API that we connect in our Swarm environment allows us to do orchestration by creating tasks for each service. The task allocation will enable us to allocate work to tasks via their IP address. The dispatcher and scheduler assign and instruct worker nodes to run a task.The overlay network driver creates a distributed network among multiple Docker daemon hosts. This network sits on top of overlays the host-specific networks, allowing containers connected to it including swarm service containers to communicate securely when encryption is enabled.

Docker transparently handles routing of each packet to and from the correct Docker daemon host and the correct destination container. When you initialize a swarm or join a Docker host to an existing swarm, two new networks are created on that Docker host:.

You can create user-defined overlay networks using docker network createin the same way that you can create user-defined bridge networks.

Services or containers can be connected to more than one network at a time. Services or containers can only communicate across networks they are each connected to. Although you can connect both swarm services and standalone containers to an overlay network, the default behaviors and configuration concerns are different. For that reason, the rest of this topic is divided into operations that apply to all overlay networks, those that apply to swarm service networks, and those that apply to overlay networks used by standalone containers.

You need the following ports open to traffic to and from each Docker host participating on an overlay network:. Before you can create an overlay network, you need to either initialize your Docker daemon as a swarm manager using docker swarm init or join it to an existing swarm using docker swarm join.

Either of these creates the default ingress overlay network which is used by swarm services by default. You need to do this even if you never plan to use swarm services. Afterward, you can create additional user-defined overlay networks.

To create an overlay network which can be used by swarm services or standalone containers to communicate with other standalone containers running on other Docker daemons, add the --attachable flag:.

synapse docker swarm

You can specify the IP address range, subnet, gateway, and other options. See docker network create --help for details. Manager nodes in the swarm rotate the key used to encrypt gossip data every 12 hours. To encrypt application data as well, add --opt encrypted when creating the overlay network.

This encryption imposes a non-negligible performance penalty, so you should test this option before using it in production. When you enable overlay encryption, Docker creates IPSEC tunnels between all the nodes where tasks are scheduled for services attached to the overlay network. Overlay network encryption is not supported on Windows. If a Windows node attempts to connect to an encrypted overlay network, no error is detected but the node cannot communicate.

You can use the overlay network feature with both --opt encrypted --attachable and attach unmanaged containers to that network:. Most users never need to configure the ingress network, but Docker allows you to do so.

This can be useful if the automatically-chosen subnet conflicts with one that already exists on your network, or you need to customize other low-level network settings such as the MTU. Customizing the ingress network involves removing and recreating it. This is usually done before you create any services in the swarm. If you have existing services which publish ports, those services need to be removed before you can remove the ingress network.

During the time that no ingress network exists, existing services which do not publish ports continue to function but are not load-balanced. This affects services which publish ports, such as a WordPress service which publishes port Inspect the ingress network using docker network inspect ingressand remove any services whose containers are connected to it.

These are services that publish ports, such as a WordPress service which publishes port If all such services are not stopped, the next step fails. Create a new overlay network using the --ingress flag, along with the custom options you want to set. This example sets the MTU tosets the subnet to Note : You can name your ingress network something other than ingressbut you can only have one.Your Bet Credits are non-withdrawable, and Bet Credits stakes are not included in any returns.
