Upgrade the operator to use Operator SDK v1.33.0 (#182)
* Move controller package inside internal directory Based on the go/v4 project structure, the following changed: - Pakcage `controllers` is now named `controller` - Package `controller` now lives inside new `internal` directory * Move main.go in cmd directory Based on the new go/v4 project structure, `main.go` now lives in the `cmd` directory. * Change package import in main.go * Update go mod dependencies Update the dependencies based on the versions obtained by creating a new operator project using `kubebuilder init --domain onepassword.com --plugins=go/v4`. This is based on the migration steps provided to go from go/v3 to go/v4 (https://book.kubebuilder.io/migration/migration_guide_gov3_to_gov4) * Update vendor * Adjust code for breaking changes from pkg update sigs.k8s.io/controller-runtime package had breaking changes from v0.14.5 to v0.16.3. This commit brings the changes needed to achieve the same things using the new functionality avaialble. * Adjust paths to connect yaml files Since `main.go` is now in `cmd` directory, the paths to the files for deploying Connect have to be adjusted based on the new location `main.go` is executed from. * Update files based on new structure and scaffolding These changes are made based on the new project structure and scaffolding obtained when using the new go/v4 project structure. These were done based on the migration steps mentioned when migrating to go/v4 (https://book.kubebuilder.io/migration/migration_guide_gov3_to_gov4). * Update config files These updates are made based on the Kustomize v4 syntax. This is part of the upgrate to go/v4 (https://book.kubebuilder.io/migration/migration_guide_gov3_to_gov4) * Update dependencies and GO version * Update vendor * Update Kubernetes tools versions * Update operator version in Makefile Now the version in the Makefile matches the version of the operator * Update Operator SDK version in version.go * Adjust generated deepcopy It seems that the +build tag is no longer needed based on the latest generated scaffolding, therefore it's removed. * Update copyright year * Bring back missing changes from migration Some customization in Makefile was lost during the migration process. Specifically, the namespace customization for `make deploy` command. Also, we push changes to kustomization.yaml for making the deploy process smoother. * Add RBAC perms for coordination.k8s.io It seems that with the latest changes to Kubernetes and Kustomize, we need to add additional RBAC to the service account used so that it can properly access the `leases` resource. * Optimize Dockerfile Dockerfile had a step for caching dependencies (go mod download). However, this is already done by the vendor directory, which we include. Therefore, this step can be removed to make the image build time faster.

## Code of Conduct
|
||||
|
||||
This project and everyone participating in it is governed by the
|
||||
[mergo Code of Conduct](https://github.com/imdario/mergoblob/master/CODE_OF_CONDUCT.md).
|
||||
By participating, you are expected to uphold this code. Please report unacceptable behavior
|
||||
to <>.
|
||||
|
||||
|
||||
## I Have a Question
|
||||
|
||||
> If you want to ask a question, we assume that you have read the available [Documentation](https://pkg.go.dev/github.com/imdario/mergo).
|
||||
|
||||
Before you ask a question, it is best to search for existing [Issues](https://github.com/imdario/mergo/issues) that might help you. In case you have found a suitable issue and still need clarification, you can write your question in this issue. It is also advisable to search the internet for answers first.
|
||||
|
||||
If you then still feel the need to ask a question and need clarification, we recommend the following:
|
||||
|
||||
- Open an [Issue](https://github.com/imdario/mergo/issues/new).
|
||||
- Provide as much context as you can about what you're running into.
|
||||
- Provide project and platform versions (nodejs, npm, etc), depending on what seems relevant.
|
||||
|
||||
We will then take care of the issue as soon as possible.
|
||||
|
||||
## I Want To Contribute

|
||||
> ### Legal Notice <!-- omit in toc -->
|
||||
> When contributing to this project, you must agree that you have authored 100% of the content, that you have the necessary rights to the content and that the content you contribute may be provided under the project license.

### Reporting Bugs
|
||||
|
||||
<!-- omit in toc -->
|
||||
#### Before Submitting a Bug Report
|
||||
|
||||
A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to investigate carefully, collect information and describe the issue in detail in your report. Please complete the following steps in advance to help us fix any potential bug as fast as possible.
|
||||
|
||||
- Make sure that you are using the latest version.
|
||||
- Determine if your bug is really a bug and not an error on your side e.g. using incompatible environment components/versions (Make sure that you have read the [documentation](). If you are looking for support, you might want to check [this section](#i-have-a-question)).
|
||||
- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/imdario/mergoissues?q=label%3Abug).
|
||||
- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue.
|
||||
- Collect information about the bug:
|
||||
- Stack trace (Traceback)
|
||||
- OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
|
||||
- Version of the interpreter, compiler, SDK, runtime environment, package manager, depending on what seems relevant.
|
||||
- Possibly your input and the output
|
||||
- Can you reliably reproduce the issue? And can you also reproduce it with older versions?
|
||||
|
||||
<!-- omit in toc -->
|
||||
#### How Do I Submit a Good Bug Report?
|
||||
|
||||
> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. Instead sensitive bugs must be sent by email to .
|
||||
<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->
|
||||
|
||||
We use GitHub issues to track bugs and errors. If you run into an issue with the project:
|
||||
|
||||
- Open an [Issue](https://github.com/imdario/mergo/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
|
||||
- Explain the behavior you would expect and the actual behavior.
|
||||
- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
|
||||
- Provide the information you collected in the previous section.
|
||||
|
||||
Once it's filed:
|
||||
|
||||
- The project team will label the issue accordingly.
|
||||
- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
|
||||
- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be implemented by someone.
|
||||
|
||||
### Suggesting Enhancements
|
||||
|
||||
This section guides you through submitting an enhancement suggestion for mergo, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
|
||||
|
||||
<!-- omit in toc -->
|
||||
#### Before Submitting an Enhancement
|
||||
|
||||
- Make sure that you are using the latest version.
|
||||
- Read the [documentation]() carefully and find out if the functionality is already covered, maybe by an individual configuration.
|
||||
- Perform a [search](https://github.com/imdario/mergo/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
|
||||
- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
|
||||
|
||||
<!-- omit in toc -->
|
||||
#### How Do I Submit a Good Enhancement Suggestion?
|
||||
|
||||
Enhancement suggestions are tracked as [GitHub issues](https://github.com/imdario/mergo/issues).
|
||||
|
||||
- Use a **clear and descriptive title** for the issue to identify the suggestion.
|
||||
- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
|
||||
- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
|
||||
- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux. <!-- this should only be included if the project has a GUI -->
|
||||
- **Explain why this enhancement would be useful** to most mergo users. You may also want to point out the other projects that solved it better and which could serve as inspiration.

A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
|
||||
|
||||
Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
|
||||

||||

### Latest release
|
||||
|
||||
[Release v0.3.6](https://github.com/imdario/mergo/releases/tag/v0.3.6).
|
||||
|
||||
### Important note
|
||||
|
||||
Please keep in mind that a problematic PR broke [0.3.9](//github.com/imdario/mergo/releases/tag/0.3.9). I reverted it in [0.3.10](//github.com/imdario/mergo/releases/tag/0.3.10), and I consider it stable but not bug-free. Also, this version adds support for go modules.
|
||||
Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.

|
||||

||||
If you were using Mergo before April 6th, 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause in existing projects after the change (release 0.2.0).

## Usage
|
||||
|
||||
You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are zero values](https://golang.org/ref/spec#The_zero_value) too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).

/*
|
||||
A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
|
||||
Package mergo merges same-type structs and maps by setting default values in zero-value fields.
|
||||
|
||||
Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
|
||||
|
||||
Status
|
||||
|
||||
It is ready for production use. It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc.
|
||||
|
||||
Important note
|
||||
|
||||
Please keep in mind that a problematic PR broke 0.3.9. We reverted it in 0.3.10. We consider 0.3.10 as stable but not bug-free. . Also, this version adds suppot for go modules.
|
||||
|
||||
Keep in mind that in 0.3.2, Mergo changed Merge() and Map() signatures to support transformers. We added an optional/variadic argument so that it won't break the existing code.
|
||||
|
||||
If you were using Mergo before April 6th, 2015, please check your project works as intended after updating your local copy with go get -u github.com/imdario/mergo. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause in existing projects after the change (release 0.2.0).
|
||||
|
||||
Install
|
||||
|
||||
Do your usual installation procedure:
|
||||
|
||||
go get github.com/imdario/mergo
|
||||
|
||||
// use in your .go code
|
||||
import (
|
||||
"github.com/imdario/mergo"
|
||||
)
|
||||
Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
|
||||
|
||||
Usage
|
||||
|
||||
You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as they are zero values too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
|
||||
From my own work-in-progress project:
|
||||
|
||||
if err := mergo.Merge(&dst, src); err != nil {
|
||||
// ...
|
||||
type networkConfig struct {
|
||||
Protocol string
|
||||
Address string
|
||||
ServerType string `json: "server_type"`
|
||||
Port uint16
|
||||
}
|
||||
|
||||
Also, you can merge overwriting values using the transformer WithOverride.
|
||||
|
||||
if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
|
||||
// ...
|
||||
type FssnConfig struct {
|
||||
Network networkConfig
|
||||
}
|
||||
|
||||
Additionally, you can map a map[string]interface{} to a struct (and otherwise, from struct to map), following the same restrictions as in Merge(). Keys are capitalized to find each corresponding exported field.
|
||||
|
||||
if err := mergo.Map(&dst, srcMap); err != nil {
|
||||
// ...
|
||||
var fssnDefault = FssnConfig {
|
||||
networkConfig {
|
||||
"tcp",
|
||||
"127.0.0.1",
|
||||
"http",
|
||||
31560,
|
||||
},
|
||||
}
|
||||
|
||||
Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as map[string]interface{}. They will be just assigned as values.
|
||||
// Inside a function [...]
|
||||
|
||||
Here is a nice example:
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/imdario/mergo"
|
||||
)
|
||||
|
||||
type Foo struct {
|
||||
A string
|
||||
B int64
|
||||
if err := mergo.Merge(&config, fssnDefault); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
func main() {
|
||||
src := Foo{
|
||||
A: "one",
|
||||
B: 2,
|
||||
}
|
||||
dest := Foo{
|
||||
A: "two",
|
||||
}
|
||||
mergo.Merge(&dest, src)
|
||||
fmt.Println(dest)
|
||||
// Will print
|
||||
// {two 2}
|
||||
}
|
||||
|
||||
Transformers
|
||||
|
||||
Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, time.Time is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero time.Time?
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/imdario/mergo"
|
||||
"reflect"
|
||||
"time"
|
||||
)
|
||||
|
||||
type timeTransformer struct {
|
||||
}
|
||||
|
||||
func (t timeTransformer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
|
||||
if typ == reflect.TypeOf(time.Time{}) {
|
||||
return func(dst, src reflect.Value) error {
|
||||
if dst.CanSet() {
|
||||
isZero := dst.MethodByName("IsZero")
|
||||
result := isZero.Call([]reflect.Value{})
|
||||
if result[0].Bool() {
|
||||
dst.Set(src)
|
||||
}
|
||||
}
|
||||
return nil
|
||||
}
|
||||
}
|
||||
return nil
|
||||
}
|
||||
|
||||
type Snapshot struct {
|
||||
Time time.Time
|
||||
// ...
|
||||
}
|
||||
|
||||
func main() {
|
||||
src := Snapshot{time.Now()}
|
||||
dest := Snapshot{}
|
||||
mergo.Merge(&dest, src, mergo.WithTransformers(timeTransformer{}))
|
||||
fmt.Println(dest)
|
||||
// Will print
|
||||
// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
