  • learn about is SSHKit and the various methods it provides
  • SSHKit was actually developed and released with Capistrano 3, and it’s basically a lower-level tool that provides methods for connecting and interacting with remote servers
  • on(): specifies the server to run on
  • within(): specifies the directory path to run in
  • with(): specifies the environment variables to run with
  • run on the application server
  • within the path specified
  • with certain environment variables set
  • execute(): the workhorse that runs the commands on your server
  • upload(): uploads a file from your local computer to your remote server
  • capture(): executes a command and returns its output as a string

      capture 是跑在遠端伺服器上
  • upload() has the bang symbol (!) because that’s how it’s defined in SSHKit, and it’s just a convention letting us know that the method will block until it finishes.
  • But in order to ensure rake runs with the proper environment variables set, we have to use rake as a symbol and pass db:seed as a string
  • This format will also be necessary whenever you’re running any other Rails-specific commands that rely on certain environment variables being set
  • I recommend you take a look at SSHKit’s example page to learn more
  • make sure we pushed all our local changes to the remote master branch
  • run this task before Capistrano runs its own deploy task
  • actually creates three separate tasks
  • I created a namespace called deploy to contain these tasks since that’s what they’re related to.
  • we’re using the callbacks inside a namespace to make sure Capistrano knows which tasks the callbacks are referencing.
  • custom recipe (a Capistrano term meaning a series of tasks)
  • /shared: holds files and directories that persist throughout deploys
  • When you run cap production deploy, you’re actually calling a Capistrano task called deploy, which then sequentially invokes other tasks
  • your favorite browser (I hope it’s not Internet Explorer)
  • Deployment is hard and takes a while to sink in.
  • the most important thing is to not get discouraged

docker cluster system server HA

shared by 張 旭 on 16 Jun 17 - No Cached
  • The cluster management and orchestration features embedded in the Docker Engine are built using SwarmKit.
  • Docker engines participating in a cluster are running in swarm mode
  • A swarm is a cluster of Docker engines, or nodes, where you deploy services
  • ...19 more annotations...
  • When you run Docker without using swarm mode, you execute container commands.
  • When you run the Docker in swarm mode, you orchestrate services.
  • You can run swarm services and standalone containers on the same Docker instances.
  • A node is an instance of the Docker engine participating in the swarm
  • You can run one or more nodes on a single physical computer or cloud server
  • To deploy your application to a swarm, you submit a service definition to a manager node.
  • Manager nodes also perform the orchestration and cluster management functions required to maintain the desired state of the swarm.
  • Manager nodes elect a single leader to conduct orchestration tasks.
  • Worker nodes receive and execute tasks dispatched from manager nodes.
  • service is the definition of the tasks to execute on the worker nodes
  • When you create a service, you specify which container image to use and which commands to execute inside running containers.
  • replicated services model, the swarm manager distributes a specific number of replica tasks among the nodes based upon the scale you set in the desired state.
  • global services, the swarm runs one task for the service on every available node in the cluster.
  • A task carries a Docker container and the commands to run inside the container
  • Manager nodes assign tasks to worker nodes according to the number of replicas set in the service scale.
  • Once a task is assigned to a node, it cannot move to another node
  • If you do not specify a port, the swarm manager assigns the service a port in the 30000-32767 range.
  • External components, such as cloud load balancers, can access the service on the PublishedPort of any node in the cluster whether or not the node is currently running the task for the service.
  • Swarm mode has an internal DNS component that automatically assigns each service in the swarm a DNS entry.

aws docker system

shared by 張 旭 on 08 Oct 18 - No Cached
  • Cloudstor is a modern volume plugin built by Docker
  • Docker swarm mode tasks and regular Docker containers can use a volume created with Cloudstor to mount a persistent data volume.
  • Global shared Cloudstor volumes mounted by all tasks in a swarm service.
  • ...14 more annotations...
  • Workloads running in a Docker service that require access to low latency/high IOPs persistent storage, such as a database engine, can use a relocatable Cloudstor volume backed by EBS.
  • Each relocatable Cloudstor volume is backed by a single EBS volume.
  • If a swarm task using a relocatable Cloudstor volume gets rescheduled to another node within the same availability zone as the original node where the task was running, Cloudstor detaches the backing EBS volume from the original node and attaches it to the new target node automatically.
  • in a different availability zone,
  • Cloudstor transfers the contents of the backing EBS volume to the destination availability zone using a snapshot, and cleans up the EBS volume in the original availability zone.
  • Typically the snapshot-based transfer process across availability zones takes between 2 and 5 minutes unless the work load is write-heavy.
  • A swarm task is not started until the volume it mounts becomes available
  • Sharing/mounting the same Cloudstor volume backed by EBS among multiple tasks is not a supported scenario and leads to data loss.
  • a Cloudstor volume to share data between tasks, choose the appropriate EFS backed shared volume option.
  • When multiple swarm service tasks need to share data in a persistent storage volume, you can use a shared Cloudstor volume backed by EFS.
  • a volume and its contents can be mounted by multiple swarm service tasks without the risk of data loss
  • over NFS
  • the persistent data backed by EFS volumes is always available.
  • shared Cloudstor volumes only work in those AWS regions where EFS is supported.

shared by 張 旭 on 07 Sep 18 - No Cached
  • a service is the image for a microservice within the context of some larger application.
  • When you create a service, you specify which container image to use and which commands to execute inside running containers.
  • an overlay network for the service to connect to other services in the swarm
  • ...13 more annotations...
  • In the swarm mode model, each task invokes exactly one container
  • A task is analogous to a “slot” where the scheduler places a container.
  • A task is the atomic unit of scheduling within a swarm.
  • A task is a one-directional mechanism. It progresses monotonically through a series of states: assigned, prepared, running, etc.
  • Docker swarm mode is a general purpose scheduler and orchestrator.
  • Hypothetically, you could implement other types of tasks such as virtual machine tasks or non-containerized process tasks.
  • If all nodes are paused or drained, and you create a service, it is pending until a node becomes available.
  • reserve a specific amount of memory for a service.
  • impose placement constraints on the service
  • As the administrator of a swarm, you declare the desired state of your swarm, and the manager works with the nodes in the swarm to create that state.
  • two types of service deployments, replicated and global.
  • A global service is a service that runs one task on every node.
  • Good candidates for global services are monitoring agents, an anti-virus scanners or other types of containers that you want to run on every node in the swarm.

  • Since source code changes often, the previously cached layer for the ADD instruction is invalidated due to the mismatching checksums.
  • The ARG instruction in the Dockerfile defines RAILS_ENV variable and is implicitly used as an environment variable by the rest of the instructions defined just after that ARG instruction.
  • RUN instructions are used to install gems and precompile static assets using sprockets
  • Instead, Docker automatically re-uses the previously built layer for the RUN bundle install instruction if the Gemfile.lock file remains unchanged.
  • everyday we need to build a lot of Docker images containing source code from varying Git branches as well as with varying environments.
  • it is hard for Docker to cache layers for bundle install and rake assets:precompile tasks and re-use those layers during every docker build command run with different application source code and a different environment.
  • By default, Bundler installs gems at the location which is set by Rubygems.

  • All of these task runners (or build systems if you want to call them that) try to abstract some kind of task paradigm away into their own siloed incantations.
  • Gulp isn't the only culprit either; Jake, Broccoli, Brunch and Mimosa all require plugins to install as well, which means when using any of these task runners, you're essentially just installing 1 more dependency (the task runner) than if you had no task runner, and just used each of the projects own binaries
