Postgres Update Json FileYou can use our source code if you want to support a different backing service any networked attached service that your application consumes to do its job, for example a Mongo. DB instance or a Postgre. SQL database. Characteristics of GOV. UK Paa. SThis table summarises the core characteristics of the Paa. S offering. Paa. S characteristic. Meaning. Multi tenant architecture. Applications running on the platform are isolated from each other and cant read or change each others code, data or logs eg the Digital Marketplace application cant access the data of the GOV. UK publishing platform. Application development teams manage their own user support. A platform where people developing applications also support the application out of hours leads to better software and a better user experience. Self service model. Paa. S makes it easy for development teams to get started, and to make frequent changes to their applications without requiring support from a member of the Paa. S team eg they can create a Postgres instance. Because application teams have this complete control, they wont experience any unnecessary delays. Can use multiple public clouds. Paa. S isnt locked into a single provider in order to encourage price competition, and to also remove the risk of a single point of failure. Technology. GOV. UK Paa. S uses Cloud Foundry and Amazon Web Services AWS. Cloud Foundry. The Paa. S platform is built using the open source Cloud Foundry project. Multiple open source products were evaluated before Cloud Foundry was selected as the best fit for Paa. S. We chose Cloud Foundry due to its maturity and because it offered a selection of user permissions support for a wide variety of languages and frameworks through buildpacks a very active community an ability to scale easily, performing well under heavy load. For more information on why we chose Cloud Foundry, read our blog post. GOV. UK Paa. S addresses common usability, security, compliance and scalability concerns experienced by government development teams. This makes the platform a superior option to your development team deploying their own version of the Cloud Foundry software, where theyd need to address cloud security implications and build a continuous integration pipeline. Amazon Web Services. Currently GOV. UK Paa. S runs on Amazon Web Services. As a tenant, you do not have to interact with AWS directly all interactions required to deploy and manage your service are carried out through Cloud Foundry commands. The platform may change cloud provider in the future, depending on cost. Your interface to the Paa. S will always remain the same, no matter which provider is in use. Pricing. GOV. UK Paa. S will initially operate using a freemium pricing model. We will select underlying hosting providers with cost in mind. We can change to a more competitively priced hosting provider without changing how you interface with the Paa. S. Please contact us for pricing details at gov uk paas supportdigital. Get started. Paa. S requirements. To be hosted by GOV. UK Paa. S, your application must follow the twelve factor application principles described in more detail below this will be the case if your app was written to be deployed to another Paa. S like Herokunot carry data at SECRET or above this is currently out of scope for GOV. UK Paa. Sbe build using a supported buildpack or written in one of these languages. Go. Nodejs. Java. PHPPython. Rubystatic HTMLCSSJavascript site. Cloud Foundry buildpacks provide runtime and framework support for your application. For most languages, you will need to provide configuration files to describe your apps dependencies. Note that most buildpacks will support a limited range of versions of the language. These principles were formulated by Adam Wiggins, the cofounder of the Heroku platform. They outline practices for modern apps to follow during development to make them scalable and easy to deploy. Your app must follow these practices to work on the Cloud Foundry technology which is used by GOV. UK Paa. S. We have summarised the practices in the table below, and noted the relevance of each principle to GOV. UK Paa. S. Visit the 1. Principle. Meaning. Relevance to Cloud Foundry. One codebase many deploys. Each of your applications needs its own source controlled repository. You can push the same codebase to many Cloud Foundry applications with these commands cf push myapp staging cf push myapp production. Isolate dependencies. All required dependencies eg a database or image library must be vendored into your software system. If you dont declare your dependencies, you probably wont be able to deploy your application on Cloud Foundry. How you specify dependencies depends on which language and buildpack you use. For example, the python buildpack expects you to provide a requirements. Store your configuration in the environment. Ensure you separate the storage of your code and configuration this is anything that may vary between environments, such as passwords. Cloud Foundry provides environment variables to tell an application how to configure itself, e. VCAPSERVICES tells applications what services are available and how to connect to them. You can create your own environment variables for each application. Backing Services. All your backing services e. A change in service should not require a code change. In Cloud Foundry, backing services are referred to as services. Users can create services, bind them to applications, and delete them. Best practices for writing Dockerfiles. Estimated reading time. Docker can build images automatically by reading the instructions from a. Dockerfile, a text file that contains all the commands, in order, needed to. Dockerfiles adhere to a specific format and use a. You can learn the basics on the. Dockerfile Reference page. If. youre new to writing Dockerfiles, you should start there. This document covers the best practices and methods recommended by Docker. Inc. and the Docker community for building efficient images. To see many of. these practices and recommendations in action, check out the Dockerfile for. Note for more detailed explanations of any of the Dockerfile commands. Dockerfile Reference page.

In addition to using a. Use multi stage builds. If you use Docker 1. Avoid installing unnecessary packages. In order to reduce complexity, dependencies, file sizes, and build times, you. For example, you dont need to include a text editor. Each container should have only one concern. Decoupling applications into multiple containers makes it much easier to scale. For instance, a web application stack might. You may have heard that there should be one process per container. While this. mantra has good intentions, it is not necessarily true that there should be only. In addition to the fact that. For. instance, Celery can spawn multiple worker. Apache might create a process per. While one process per container is frequently a good rule of thumb. Use your best judgment to keep containers as. If containers depend on each other, you can use Docker container networks. Minimize the number of layers. Prior to Docker 1. Docker 1. 1. 0, it was important. The following improvements have. In Docker 1. 1. 0 and higher, only RUN, COPY, and ADD instructions create. Other instructions create temporary intermediate images, and no longer. Docker 1. 7. 0. 5 and higher add support for. This allows you to include tools and. Sort multi line arguments. Whenever possible, ease later changes by sorting multi line arguments. This will help you avoid duplication of packages and make the. This also makes PRs a lot easier to read and. Adding a space before a backslash helps as well. Heres an example from the buildpack deps image RUN apt get update apt get install y. Build cache. During the process of building an image Docker will step through the. Dockerfile executing each in the order specified. As each instruction is examined Docker will look for an existing image in its. If you do not want to use the cache at all you can use the no cachetrue. However, if you do let Docker use its cache then it is very important to. The basic rules. that Docker will follow are outlined below Starting with a parent image that is already in the cache, the next. If. not, the cache is invalidated. In most cases simply comparing the instruction in the Dockerfile with one. However, certain instructions require. For the ADD and COPY instructions, the contents of the files. The last modified and last accessed times of the files are not considered in. During the cache lookup, the checksum is compared against the. If anything has changed in the files, such. Aside from the ADD and COPY commands, cache checking will not look at the. For example, when processing. RUN apt get y update command the files updated in the container. In that case just. Once the cache is invalidated, all subsequent Dockerfile commands will. The Dockerfile instructions. Below youll find recommendations for the best way to write the. Dockerfile. FROMDockerfile reference for the FROM instruction. Whenever possible, use current Official Repositories as the basis for your. We recommend the Debian image. LABELUnderstanding object labels. You can add labels to your image to help organize images by project, record. For each. label, add a line beginning with LABEL and with one or more key value pairs. The following examples show the different acceptable formats. Explanatory comments are included inline. Note If your string contains spaces, it must be quoted or the spaces. If your string contains inner quote characters, escape. Set one or more individual labels. LABELcom. example. LABELvendorACME IncorporatedLABELcom. LABELcom. example. An image can have more than one label. Prior to Docker 1. LABEL instruction, to prevent extra layers. This is no longer necessary, but combining labels is still. Set multiple labels on one line.

As always, to make your Dockerfile more readable, understandable, and. RUN statements on multiple lines separated. Probably the most common use case for RUN is an application of apt get. The. RUN apt get command, because it installs packages, has several gotchas to look. You should avoid RUN apt get upgrade or dist upgrade, as many of the. If a package contained in the parent image is out of date, you should contact its. If you know theres a particular package, foo, that needs to be updated, use. Always combine RUN apt get update with apt get install in the same RUN. For example RUN apt get update apt get install y. Using apt get update alone in a RUN statement causes caching issues and. For example, say you have a Dockerfile FROM ubuntu 1. RUN apt get update. RUN apt get install y curl. After building the image, all layers are in the Docker cache. Suppose you later. FROM ubuntu 1. 4. RUN apt get update. RUN apt get install y curl nginx. Docker sees the initial and modified instructions as identical and reuses the. As a result the apt get update is NOT executed. Because the apt get update is not. Using RUN apt get update apt get install y ensures your Dockerfile. This technique is known as cache busting. You can also achieve. This is known as version pinning. RUN apt get update apt get install y. Version pinning forces the build to retrieve a particular version regardless of. This technique can also reduce failures due to unanticipated changes. Below is a well formed RUN instruction that demonstrates all the apt get. RUN apt get update apt get install y.
