### Post-Update Options
You might be interested in the following `postUpdateOptions`:
<!--
TODO: remove ignore
prettier & markdownlint conflicting nested list format
see: https://github.com/renovatebot/renovate/pull/30608
-->
<!-- prettier-ignore -->
1. `gomodTidy` - if you'd like Renovate to run `go mod tidy` after every update before raising the PR
1. This is implicitly enabled for major updates if the user has enabled the option `gomodUpdateImportPaths`
1. `gomodTidy1.17` - if you'd like Renovate to run `go mod tidy -compat=1.17` after every update before raising the PR
1. `gomodTidyE` - if you'd like Renovate to run `go mod tidy -e` after every update before raising the PR
1. `gomodUpdateImportPaths` - if you'd like Renovate to update your source import paths on major updates before raising the PR
1. `gomodMassage` - to enable massaging of all `replace` statements prior to running `go` so that they will be ignored
When Renovate is running using `binarySource=docker` (such as in the Mend Renovate App) then it will pick the latest compatible version of Go to run, i.e. the latest `1.x` release.
Even if the `go.mod` has a version like `go 1.22`, Renovate will treat it as a `^1.22` constraint and not `=1.22`.
Indirect updates are disabled by default. To enable them, add a package rule such as:
```json
{
"packageRules": [
{
"matchManagers": ["gomod"],
"matchDepTypes": ["indirect"],
"enabled": true
}
]
}
```
### Private Modules Authentication
Before running the `go` commands to update the `go.sum`, Renovate exports `git` [`insteadOf`](https://git-scm.com/docs/git-config#Documentation/git-config.txt-urlltbasegtinsteadOf) directives in environment variables.
The following logic is executed prior to "artifacts" updating:
The token from the `hostRules` entry matching `hostType=github` and `matchHost=api.github.com` is added as the default authentication for `github.com`.
For those running against `github.com`, this token will be the default platform token.
Next, all `hostRules` with both a token or username/password and `matchHost` will be fetched, except for any github.com one from above.
Rules from this list are converted to environment variable directives if they match _any_ of the following characteristics:
- No `hostType` is defined, or
- `hostType` is `go`, or
- `hostType` is a platform (`github`, `gitlab`, `azure`, etc.)
### Major upgrades of dependencies
Major upgrades in Go are different from most other ecosystems, because both the version and module name need to be changed.
It is very common that such upgrades require changes to application code, which Renovate doesn't do.
By default, Renovate will make such change in the `go.mod` files but nothing else - the rest is up to you.
If you add `gomodUpdateImportPaths` to `postUpdateOptions` then Renovate will also use a third-party tool to migrate import paths within application code, but there may still be actual application logic which needs to be changed too.
Ultimately: it is known and unavoidable that the majority of major Go upgrades won't be immediately mergeable.
You might prefer to configure such major updates with `dependencyDashboardApproval=true` so that you can request them on demand, on supported platforms.
