* Safely access/mutate fargate coredns pod annotations Prior to this patch, the `pkg/fargate/coredns` package had some bits of code that accessed/mutated pod annotations assuming that they'll always be instantiated correctly. This patch adds utility functions to safely mutate and access fargate pod annotations. Signed-off-by: Amine Hilaly <hilalyamine@gmail.com> * Fix generating presigned URL for K8s authentication With `aws-sdk-go-v2@1.24.1`, API server requests containing URLs presigned by `sts.PresignClient` fail with an `Unauthorized` error. `aws-sdk-go-v2@1.24.1` adds an extra header `amz-sdk-request` to the generated request, but this header is not allow-listed by `aws-iam-authenticator` server running on the control plane. This is likely due to [this change](aws/aws-sdk-go-v2#2438) which reorders the middleware operations to execute `RetryMetricsHeader` before `Signing`. This changelist removes the `RetryMetricsHeader` middleware from the stack when constructing `sts.PresignClient`. * Add release notes for 0.168.0 * Prepare for next development iteration * Handle unordered public endpoint CIDRs from EKS in endpoint updates For some clusters, EKS can return the list of public endpoint CIDRs out of order, and won't allow updates where the incoming and current sets have set equality (i.e. regardless of order of CIDR entries). This change restores the set equality check that was removed in commit 72605fb and adds an additional test case to cover this case. * Fix outdated links * Fix StringLike condition key for ebsCSIController IAM policy The IAM condition key StringLike was used incorrectly in the policy and it doesn't work with wildcard (*) in the key itself. Wildcard is only supported in the value of the key. This fixes issue in cases where a volume dynamically provisioned via the older in-tree CSI plugin is being deleted by the new EBS CSI driver, because such volumes don't have the tags used in the policy. The changes made are inspired from the AWS managed AmazonEBSCSIDriverPolicy. * Fix coredns pdb preventing cluster deletion * Add support for EKS 1.29 * Add release notes for 0.169.0 * Prepare for next development iteration * Update arm-support.md * Expand Karpenter settings.aws block to settings for v0.33.0 and greater * Update stale.yml * docs(fargate): eksctl update command is deprecated * Fix deleting cluster sometimes drain managed nodegroups * Update userdocs on nodegroups * Update release drafter template * Add support for Access Entry Type * Update access entries userdocs * Add release notes for 0.170.0 * Prepare for next development iteration * Improve userdocs layout * Announce eksctl Support Status Update * Add support for Ubuntu 22.04 based EKS images Ubuntu switched to 22.04 (Jammy) based images for EKS >= 1.29 . Add support for that here. * Add release notes for 0.171.0 * Prepare for next development iteration * Changed the error to more understandable when the region code isn't set * Fix checks for updated addon versions When executing `eksctl get addons` an available update is not shown if the only change to the version string is the `eksbuild` number, e.g. `v1.0.0-eksbuild.2` is not shown as an update of `v1.0.0-eksbuild.1`. The `findNewerVersions` func in `pkg/actions/get.go` had code to explicitly ignore anything after the patch number. So `v1.1.0-eksbuild.1` and `v1.1.0-eksbuild.4` were both converted to `1.1.0` and considered equal. This fix removes the code that explicitly ignores the `-eksbuild.x` portion of the version and allows the `semver` package to compare the full version information. Tests have also been updated to better match the version strings used by AWS addons. * Extract common steps setting up build environment from workflows * Disable slack notifications * Bump actions/cache from 3.3.2 to 4.0.0 * Update userdocs dependencies * Update schema for new AMI family * Update go dependencies * Bump k8s dependencies to v0.29 Signed-off-by: Amine Hilaly <hilalyamine@gmail.com> * Replace all deprecated sets.String with generic sets.Set * Update actions dependencies Update go version to 1.21 in actions * Update build image manifest, tag file and workflows * Update build image go version to 1.21 Update build image manifest, tag file and workflows * Revert removing RetryMetricsHeader in presigned requests * Add release notes for 0.172.0 * Revert misdeleted checkout step for publishing release * Add integ test without build target * Remove unused slack token * Remove slackToken * Prepare for next development iteration * Bump dependencies for Dependabot alerts Bump github.com/go-git/go-git/v5 from 5.4.2 to 5.11.0 Bumps [github.com/go-git/go-git/v5](https://github.com/go-git/go-git) from 5.4.2 to 5.11.0. - [Release notes](https://github.com/go-git/go-git/releases) - [Commits](go-git/go-git@v5.4.2...v5.11.0) --- updated-dependencies: - dependency-name: github.com/go-git/go-git/v5 dependency-type: indirect ...

When deleting such a nodegroup, it's the user's responsibility to also delete the corresponding access entry when no more nodegroups are associated with it. This is because eksctl cannot tell if an access entry resource is still in use by non-eksctl created self-managed nodegroups. Self-managed nodegroups not using a pre-existing instanceRoleARN will continue to have the access entry resource in the CloudFormation stack, making delete nodegroup an atomic operation for most use cases.

Description
With this PR, eksctl now accounts for the possibility of a user deleting a subnet from their cluster, operation which is achieved outside eksctl. This scenario became much more likely with introduction of #7218. Deleting a cluster subnet creates a configuration drift from cloudformation stack. This means, eksctl now needs to be aware that the subnets that it imports from the cluster stack may have been deleted and thus can't be used anymore.
Additionally, this PR introduces a new validation, in which it fails early if users try to create private nodegroups (i.e. set
privateNetworking:true) in a cluster where all private subnets were deleted. Vice versa holds as-well, eksctl failing early if users try to create public nodegroups (i.e. don't setprivateNetworking:true) in a cluster where all public subnets were deleted.In terms of integration tests, I've tried adding a test on top of the spec that covers
eksctl utils update-cluster-vpc-config, but deleting subnets there proved tricky due to dependencies created earlier in the test.Fixes #7538
