Still, there are common patterns that can be copied +from other commands and projects. + +To enable postgres database support you must add `run-db` to `TEST_DEPS` and +`RUN_DEPS` variables to [Makefile.vars](Makefile.vars). + +You can also override the default setup via the `DB_HOST`, `DB_PORT`, `DB_NAME`, +`DB_USER`, and `DB_PASSWORD` variables, but this is optional. + +**Note:** when running test against a DB you usually have to extend the default +`TEST_TIMEOUT` of 10s to a less aggressive value. + +To enable AWS localstack you have to add `run-aws` to the default`TEST_DEPS` and +`RUN_DEPS` variables, as well as to add your list of required aws services to +the `AWS_SERVICES` variable. + +```Makefile +# Setup required targets before testing (default: ). +TEST_DEPS := run-aws +# Setup required targets before running commands (default: ). +RUN_DEPS := run-aws +# Setup required aws services for testing (default: ). +AWS_SERVICES := s3 sns +``` + +**Note:** Currently, the [Makefile](Makefile) does not support all command-line +arguments since make swallows arguments starting with `-`. To compensate this +shortcoming the commands need to support setup via command specific environment +variables following the principles of the [Twelf Factor App][12factor]. + +[12factor]: https://12factor.net/ + + +## Standard targets + +The [Makefile](Makefile) supports the following often used standard targets. + +```bash +make all # short cut target to init, test, and build binaries locally +make all-clean # short cut target to clean, init, test, and build binaries +make commit # short cut target to execute pre-commit lint and test steps +``` + +The short cut targets can be customized by setting up the variables `TARGETS_*` +(in upper letters), according to your preferences in `Makefile.vars` or in your ++environment. + +Other less customizable commands are targets to build, install, delete, and +cleanup project resources: + +```bash +make test # short cut to execute default test targets +make lint # short cut to execute default lint targets +make build # creates binary files of commands +make clean # removes all resource created during build +``` + +While these targets allow to execute the most important tasks out-of-the-box, +there exist a high number of specialized (sometimes project specific) commands +that provide more features with quicker response times for building, testing, +releasing, and executing of components. + +**Note:** All targets automatically trigger their preconditions and install the +latest version of the required tools, if some are missing. To enforce the setup +of a new tool, you need to run `make init` explicitly. + +The following targets are helpful to investigate the [Makefile](Makefile): + +```bash +make help # prints a short help about major target (families) +make targets # prints a list of all available targets +make show # shows the effective target implementation +``` + + +### Test targets + +Often it is more efficient or even necessary to execute the fine grained test +targets to complete a task. + +```bash +make test # short cut to execute default test targets +make test-all # executes the complete tests suite +make test-unit # executes only unit tests by setting the short flag +make test-self # executes a self-test of the build scripts +make test-cover # opens the test coverage report in the browser +make test-upload # uploads the test coverage files +make test-clean # cleans up the test files +make test-go # test go versions +``` + +In addition, it is possible to restrict test target execution to packages, +files and test cases as follows: + +* For a single package use `make test-(unit|all) ...`. +* For a single test file `make test[-(unit|all) /_test.go ...`. +* For a single test case `make test[-(unit|all) / ...`. + +The default test target can be customized by defining the `TARGETS_TEST` +variable in `Makefile.vars`. Usually this is not necessary. + + +### Linter targets + +The [Makefile](Makefile) supports different targets that help with linting +according to different quality levels, i.e. `min`,`base` (default), `plus`, +`max`, (and `all`) as well as automatically fixing the issues. + +```bash +make lint # short cut to execute default lint targets +make lint-min # lints the go-code using a minimal config +make lint-base # lints the go-code using a baseline config +make lint-plus # lints the go-code using an advanced config +make lint-max # lints the go-code using an expert config +make lint-all # lints the go-code using an insane all-in config +make lint-codacy # lints the go-code using codacy client side tools +make lint-markdown # lints the documentation using markdownlint +make lint-revive # lints the go-code using the revive standalone linter +make lint-shell # lints the sh-code using shellcheck to find issues +make lint-leaks # lints committed code using gitleaks for leaked secrets +make lint-leaks? # lints un-committed code using gitleaks for leaked secrets +make lint-vuln # lints the go-code using govulncheck to find vulnerabilities +make lint-api # lints the api specifications in '/zalando-apis' +``` + +The default target for `make lint` is determined by the selected `CODE_QUALITY` +level (`min`, `base`, `plus`, and `max`), and the `CODACY` setup (`enabled`, +`disabled`). The default setup is to run the targets `lint-base`, `lint-apis`, +`lint-markdown`, and `lint-codacy`. It can be further customized via changing +the `TARGETS_LINT` in `Makefile.vars` - if necessary. + +The `lint-*` targets for `golangci-lint` allow some command line arguments: + +1. The keyword `fix` to lint with auto fixing enabled (when supported), +2. The keyword `config` to shows the effective linter configuration, +3. The keyword `linters` to display the linters with description, or +4. `,...` comma separated list of linters to enable for a quick checks. + +The default linter config is providing a golden path with different levels +out-of-the-box, i.e. a `min` for legacy code, `base` as standard for active +projects, and `plus` for experts and new projects, and `max` enabling all +but the conflicting disabled linters. Besides, there is an `all` level that +allows to experience the full linting capability. + +Independent of the golden path this setting provides, the lint expert levels +can be customized in three ways. + +1. The default way to customize linters is adding and removing linters for all + levels by setting the `LINTERS_CUSTOM` and `LINTERS_DISABLED` variables + providing a white space separated list of linters. +2. Less comfortable and a bit trickier is the approach to override the linter + config variables `LINTERS_DISCOURAGED`, `LINTERS_DEFAULT`, `LINTERS_MINIMUM`, + `LINTERS_BASELINE`, and `LINTERS_EXPERT`, to change the standards. +3. Last the linter configs can be changed via `.golangci.yaml`, as well as + via `.codacy.yaml`, `.markdownlint.yaml`, and `revive.toml`. + +However, customizing `.golangci.yaml` and other config files is currently not +advised, since the `Makefile` is designed to update and enforce a common +version of all configs on running `update-*` targets. + + +### Build targets + +The build targets can build native as well as linux platform executables using +the default system architecture. + +```bash +make build # builds default executables (native) +make build-native # builds native executables using system architecture +make build-linux # builds linux executable using the default architecture +make build-image # builds container image (alias for image-build) +``` + +The platform and architecture of the created executables can be customized via +`BUILDOS` and `BUILDARCH` environment variables. + + +### Image targets + +Based on the convention that all binaries are installed in a single container +image, the [Makefile](Makefile) supports to create and push the container image +as required for a pipeline. + +```bash +make image # short cut for 'image-build' +make image-build # build a container image after building the commands +make image-push # pushes a container image after building it +``` + +The targets are checking silently whether there is an image at all, and whether +it should be build and pushed according to the pipeline setup. You can control +this behavior by setting `IMAGE_PUSH` to `never` or `test` to disable pushing +(and building) or enable it in addition for pull requests. Any other value will +ensure that images are only pushed for `main`-branch and local builds. + + +### Run targets + +The [Makefile](Makefile) supports targets to startup a common DB and a common +AWS container image as well as to run the commands provided by the repository. + +```bash +make run-db # runs a postgres container image to provide a DBMS +make run-aws # runs a localstack container image to simulate AWS +make run-* # runs the matched command using its before build binary +make run-go-* # runs the matched command using 'go run' +make run-image-* # runs the matched command in the container image +make run-clean # kills and removes up all running container images +make run-clean-* # kills and removes the container image of the matched command +``` + +To run commands successfully the environment needs to be setup to run the +commands in its runtim. Please visit [Running commands](#running-commands) for +more details on how to do this. + +**Note:** The DB (postgres) and AWS (localstack) containers can be used to +support any number of parallel applications, if they use different tables, +queues, and buckets. Developers are encouraged to continue with this approach +and only switch application ports and setups manually when necessary. + + +### Update targets + +The [Makefile](Makefile) supports targets for common update tasks for package +versions, for build, test, and linter tools, and for configuration files. + +```bash +make update # short cut for 'update-{go,deps,make}' +make update-all # short cut to execute all update targets +make update-go # updates the go version to the current compiler version +make update-deps # updates the project dependencies to the latest version +make update-make # updates the the build environment to the latest version +make update-tools # updates the project tools to the latest versions +``` + +Many update targets support a version with `?`-suffix to test whether an +update is available instead of executing it directly. In addition, a `major` +command line option can be used to also apply major version upgrades. + + +### Cleanup targets + +The [Makefile](Makefile) is designed to clean up everything it has created by +executing the following targets. + +```bash +make clean # short cut for clean-init, clean-build +make clean-all # cleans up all resources, i.e. also tools installed +make clean-init # cleans up all resources created by init targets +make clean-build # cleans up all resources created by build targets +make clean-run # cleans up all running container images +make clean-run-* # cleans up matched running container image +``` + + +### Install targets + +The install targets installs the latest build version of a command in the +`${GOPATH}/bin` directory for global command line execution. Usually commands +used by the project are installed automatically. + +```bash +make install # installs all software created by this project +make install-all # installs all software created by this project +make install-* # installs the matched software command or service +``` + +If a command, service, job has not been build before, it is first build. + +**Note:** Please use carefully, if your project uses common command names. + + +### Uninstall targets + +The uninstall targets remove the latest installed command from `${GOPATH}/bin`. +A full uninstall of commands used by the project can also be triggered by +`clean-all`. + +```bash +make uninstall # uninstalls all software created by this project +make uninstall-all # uninstalls all software created or used by this project +make uninstall-* # uninstalls the matched software command or service +``` + +**Note:** Please use carefully, if your project uses common command names. + + +### Release targets + +Finally, the [Makefile](Makefile) supports targets for releasing the provided +packages as library. + +```bash +make bump # bumps version to prepare a new release +make release # creates the release tags in the repository +``` + + +### Init targets + +The [Makefile](Makefile) supports initialization targets that are added as +perquisites for targets that require them. So there is usually no need to call +them manually. + + +```bash +make init # short cut for 'init-tools init-hooks init-packages' +make init-codacy # initializes the tools for running the codacy targets +make init-hooks # initializes github hooks for pre-commit, etc +make init-packages # initializes and downloads packages dependencies +make init-sources # initializes sources by generating mocks, etc +``` + + +## Compatibility + +This [Makefile](Makefile) is making extensive use of GNU tools but is supposed +to be compatible to all recent Linux and MacOS versions. Since MacOS is usually +a couple of years behind in applying the GNU standard tools, we document the +restrictions this creates here. + + +### `sed` in place substitution + +In MacOS we need to add `-e ''` after `sed -i` since else the command +section is not automatically restricted to a single argument. In linux this +restriction is automatically applied to the first argument. + + +### `realpath` not supported + +In MacOS we need to use `readlink -f` instead of `realpath`, since there may +not even be a simplified fallback of this command available.

Technically `go-make` is just a thin +wrapper around a very generic and extensible [`Makefile`](Makefile.base) that +is based on a standard [`go`][go]-project supporting different tools: + +* [`gomock`][gomock] - go generating mocks. +* [`codacy`][codacy] - for code quality documentation. +* [`golangci-lint`][golangci] - for pre-commit linting. +* [`zally`][zally] - for pre-commit API linting. +* [`gitleaks`][gitleaks] - for sensitive data scanning. +* [`grype`][grype] - for security scanning. +* [`syft`][syft] - for material listing. + +The thin wrapper provides the necessary version control for the `Makefile` and +the default config of integrated tools. It installs these tools automatically +when needed in the latest available version. + +**Note:** We except the risk that using the latest versions of tools, e.g. for +linting, may break the build for the sake of constantly updating dependencies by +default. For tools where this is not desireable, the default import can be +changed to contain a version (see [manual](MANUAL.md] for more information). + +**Warning:** `go-make` automatically installs a `pre-commit` hook overwriting +and deleting any pre-existing hook. The hook calls `go-make commit` to enforce +run unit testing and linting successfully before allowing to commit, i.e. the +goals `test-go`, `test-unit`, `lint-base` (or what code quality level is +defined as standard), and `lint-markdown`. + + +[go]: +[gomock]: +[golangci]: +[codacy]: +[zally]: +[gitleaks]: +[grype]: +[syft]: + + +## Installation + +To install `go-make` simply use the standard [`go` install][go-install] +command (or any other means, e.g. [`curl`][curl] to obtain a released binary): + +```bash +go install github.com/tkrop/go-make@latest +``` + +The scripts and configs are automatically checked out in the version matching +the wrapper. `go-make` has the following dependencies, that must be satisfied +by the runtime environment, e.g. using [`ubuntu-20.04`][ubuntu-20.04] or +[`ubuntu-22.04`][ubuntu-22.04]: + +* [GNU `make`][make] (^4.2). +* [GNU `bash`][bash] (^5.0). +* [GNU `coreutils`][core] (^8.30) +* [GNU `findutils`][find] (^4.7) +* [GNU `awk`][awk] (^5.0). +* [GNU `sed`][sed] (^4.7) +* [`curl`][curl] (^7) + +[ubuntu-20.04]: +[ubuntu-22.04]: +[go-install]: +[curl]: +[make]: +[bash]: +[core]: +[find]: +[awk]: +[sed]: + + +## Example usage + +After installing `go-make` and in the build environment, you can run all targets +by simply calling `go-make ` on the command line, in another `Makefile`, +in a github action, or any other delivery pipeline config script: + +```bash +go-make all # execute a whole build pipeline depending on the project. +go-make test lint # execute only test 'test' and 'lint' steps of a pipeline. +go-make image # execute minimal steps to create all container images. +``` + +If you like to integrate `go-make` into another `Makefile` you may find the +following template helpful: + +```Makefile +GOBIN ?= $(shell go env GOPATH)/bin +GOMAKE := github.com/tkrop/go-make@latest +TARGETS := $(shell command -v go-make >/dev/null || \ + go install $(GOMAKE) && go-make targets) + +# Include standard targets from go-make providing group targets as well as +# single target targets. The group target is used to delegate the remaining +# request targets, while the single target can be used to define the +# precondition of custom target. +.PHONY: $(TARGETS) $(addprefix target/,$(TARGETS)) +$(TARGETS):; $(GOBIN)/go-make $(MAKEFLAGS) $(MAKECMDGOALS); +$(addprefix target/,$(TARGETS)): target/%: + $(GOBIN)/go-make $(MAKEFLAGS) $*; +``` + +For further examples see [`go-make` manual](MANUAL.md). + +**Note:** To setup command completion for `go-make`add the following command to +your `.bashrc`. + +```bash +source <(go-make --completion=bash) +``` + + +## Standard `go`-Project + +The [Makefile](Makefile) provided in this project is working under the +conventions of a standard [`go`][go]-project. The standard [`go`][go]-project +is defined to meet Zalando in-house requirements, but is general enough to be +useful in open source projects too. It adheres to the following conventions: + +1. All commands (services, jobs) are provided by a `main.go` placed as usual + under `cmd` using the pattern `cmd//main.go` or in the root folder. In + the later case the project name is used as command name. + +2. All source code files and package names following the [`go`][go]-standard + only consist of lower case ascii letters, hyphens (`-`), underscores (`_`), + and dots (`.`). Files are ending with `.go` to be eligible. + +3. Modules are placed in any sub-path of the repository, e.g. in `pkg`, `app`, + `internal` are commonly used patterns, except for `build` and `run`. These + are used by `go-make` as temporary folders to build commands and run commands + and are cleaned up regularly. + +4. The build target provides build context values to setup global variables in + `main` and `config` packages. + + * `Path` - the formal package path of the command build. + * `Version` - the version as provided by the `VERSION`-file in project root + or via the `(BUILD_)VERSION` environ variables. + * `Revision` - the actual full commit hash (`git rev-parse HEAD`). + * `Build` - the current timestamp of the build (`date --iso-8601=seconds`). + * `Commit` - the timestamp of the actual commit timestamp + (`git log -1 --date=iso8601-strict --format=%cd`). + * `Dirty` - the information whether build repository had uncommitted changes. + +5. All container image build files must start with a common prefix (default is + `Dockerfile`). The image name is derived from the organization and repository + names and can contain an optional suffix, i.e `/(-)`. + +6. For running a command in a container image, make sure that the command is + installed in the default execution directory of the container image - usually + the root directory. The container image must either be generated with suffix + matching the command or without suffix. + +All targets in the `go-make` are designated to work *out-of-the-box* taking self +care to setup the [`go`][go]-project, installing the necessary tools, except for +the golang compiler and build environment (see [installation](#installation)), +and triggering the precondition targets as necessary. + + +## Terms of usage + +This software is open source as is under the MIT license.
