lib/gitlab/ci/templates/dotNET-Core.yml

+# This is a simple example illustrating how to build and test .NET Core project
+# with GitLab Continuous Integration / Continuous Delivery.
+
+# ### Specify the Docker image
+#
+# Instead of installing .NET Core SDK manually, a docker image is used 
+# with already pre-installed .NET Core SDK. 
+# The 'latest' tag targets the latest available version of .NET Core SDK image. 
+# If preferred, you can explicitly specify version of .NET Core e.g. using '2.2-sdk' tag.
+#
+# See other available tags for .NET Core: https://hub.docker.com/r/microsoft/dotnet
+# Learn more about Docker tags: https://docs.docker.com/glossary/?term=tag
+# and the Docker itself: https://opensource.com/resources/what-docker
+image: microsoft/dotnet:latest
+
+# ### Define variables
+#
+variables:
+ # 1) Name of directory where restore and build objects are stored.
+ OBJECTS_DIRECTORY: 'obj'    
+ # 2) Name of directory used for keeping restored dependencies.        
+ NUGET_PACKAGES_DIRECTORY: '.nuget'
+ # 3) A relative path to the source code from project repository root.
+ # NOTE: Please edit this path so it matches the structure of your project!
+ SOURCE_CODE_PATH: '*/*/'             
+
+# ### Define stage list
+#
+# In this example there are only two stages. 
+# Initially, the project will be built and then tested.
+stages:
+ - build
+ - test
+
+# ### Define global cache rule
+#
+# Before building the project, all dependencies (e.g. third-party NuGet packages) 
+# must be restored. Jobs on GitLab.com's Shared Runners are executed on autoscaled machines. 
+# Each machine is used only once (for security reasons) and after that it is removed. 
+# What that means is that before every job a dependency restore must be performed 
+# because restored dependencies are removed along with machines. Fortunately,
+# GitLab provides cache mechanism with the aim of keeping restored dependencies
+# for other jobs. This example shows how to configure cache to pass over restored 
+# dependencies for re-use.
+#
+# With global cache rule, cached dependencies will be downloaded before every job
+# and then unpacked to the paths as specified below.
+cache:
+ # Per-stage and per-branch caching.
+ key: "$CI_JOB_STAGE-$CI_COMMIT_REF_SLUG" 
+ paths:
+  # Specify three paths that should be cached:
+  #
+  # 1) Main JSON file holding information about package dependency tree, packages versions,
+  # frameworks etc. It also holds information where to the dependencies were restored.
+  - '$SOURCE_CODE_PATH$OBJECTS_DIRECTORY/project.assets.json'  
+  # 2) Other NuGet and MSBuild related files. Also needed.
+  - '$SOURCE_CODE_PATH$OBJECTS_DIRECTORY/*.csproj.nuget.*'    
+  # 3) Path to the directory where restored dependencies are kept.
+  - '$NUGET_PACKAGES_DIRECTORY'   
+ # 'pull-push' policy means that latest cache will be downloaded (if exists) 
+ # before executing the job, and a newer version will be uploaded afterwards. 
+ # Such setting saves time when there are no changes in referenced third-party 
+ # packages. For example if you run a pipeline with changes in your code, 
+ # but with no changes within third-party packages which your project is using, 
+ # then project restore will happen in next to no time as all required dependencies 
+ # will already be there — unzipped from cache. 'pull-push' policy is a default 
+ # cache policy, you do not have to specify it explicitly.
+ policy: pull-push 
+
+# ### Restore project dependencies
+#
+# NuGet packages by default are restored to '.nuget/packages' directory 
+# in the user's home directory. That directory is out of scope of GitLab caching. 
+# To get around this a custom path can be specified using '--packages <PATH>' option 
+# for 'dotnet restore' command. In this example a temporary directory is created 
+# in the root of project repository, so it's content can be cached.
+#
+# Learn more about GitLab cache: https://docs.gitlab.com/ee/ci/caching/index.html

+ stage: build
+ # ### Build all projects discovered from solution file. 
+ #
+ # Note: this will fail if you have any projects in your solution that are not 
+ # .NET Core based projects e.g. WCF service, which is based on .NET Framework, 
+ # not .NET Core. In such scenario you will need to build every .NET Core based 
+ # project by explicitly specifying a relative path to the directory 
+ # where it is located e.g. 'dotnet build ./src/ConsoleApp'. 
+ # Only one project path can be passed as a parameter to 'dotnet build' command.
+ script:
+  - 'dotnet build --no-restore' 
+
+tests:
+ stage: test
+ # ### Run the tests
+ #
+ # You can either run tests for all test projects that are defined in your solution 
+ # with 'dotnet test' or run tests only for specific project by specifying
+ # a relative path to the directory where it is located e.g. 'dotnet test ./test/UnitTests'. 
+ #
+ # You may want to define separate testing jobs for different types of testing
+ # e.g. integration tests, unit tests etc.
