Mattermost Cloud is a SaaS offering meant to smooth and accelerate the customer journey from trial to full adoption. There is a significant amount of friction for a customer to set up a trial of Mattermost, and even more friction to run an extended length proof of concept. Both require hardware and technical personnel resources that create a significant barrier to potential customers. Mattermost Cloud aims to remove this barrier by providing a service to provision and host Mattermost instances that can be used by customers who have no technical experience. This will accelerate the customer journey to a full adoption of Mattermost either in the form of moving to a self-hosted instance or by continuing to use the cloud service.

The following is required to properly run the cloud server.

1. Install Go
2. Install Terraform version v0.11.14
   1. Try using tfswitch for switching easily between versions
3. Install kops version 1.17.X
4. Install Helm version 2.16.X as helm and version 3.3.X as helm3 with 2to3 plugin
5. Install kubectl
6. Install golang/mock version 1.4.x

1. Specify the region in your AWS config, e.g. ~/.aws/config:

[profile mm-cloud]
region = us-east-1

2. Generate an AWS Access and Secret key pair, then export them in your bash profile:

export AWS_ACCESS_KEY_ID=YOURACCESSKEYID
export AWS_SECRET_ACCESS_KEY=YOURSECRETACCESSKEY
export AWS_PROFILE=mm-cloud

3. Create an S3 bucket to store the kops state. The name of the bucket MUST start with cloud- prefix and has to be created using the provisioner account credentials. To do it run the following:

aws s3api create-bucket --bucket cloud-<yourname>-kops-state --region us-east-1

4. Clone this repository into your GOPATH (or anywhere if you have Go Modules enabled)

Also:

• Make sure you have a key in your ~/.ssh/ such as:

  id_rsa
  id_rsa.pub
  

  If not you need to run:

  ssh-keygen -t rsa -C "<your-email>"
  

• Make sure you have helm version different than 2.16.4 as there is an issue with nginx: https://stackoverflow.com/questions/60836127/error-validation-failed-serviceaccounts-nginx-ingress-not-found-serviceacc

Simply run the following:

go install ./cmd/cloud
alias cloud='$HOME/go/bin/cloud'

Before running the server the first time you must set up the DB with:

$ cloud schema migrate

Run the server with:

cloud server --state-store=<your-s3-bucket>

tip: if you want to debug, enable --dev flag

In a different terminal/window, to create a cluster:

cloud cluster create --zones <availabiity-zone> --size SizeAlef500
i.e.
cloud cluster create --zones us-east-1c --size SizeAlef500

You will get a response like this one:

Check its creation progress on the first window where the API runs or run cloud cluster list to check cluster status

If something breaks and reprovisioning is needed, run

cloud cluster provision --cluster <cluster-ID>
i.e.
cloud clusterprovision --cluster tetw1yt3yinjdbhctsstcrybch

Then, when the state will be stable, export the kubeconfig:

kops export kubecfg <cluster-ID>-kops.k8s.local --state s3://<your-s3-bucket>
i.e.
kops export kubecfg tetw1yt3yinjdbhctsstcrybch-kops.k8s.local --state s3://angelos-kops-state

Now check if you can get the pods from the cluster with: kubectl get pods -A

To create an installation, run:

cloud installation create --owner <your-name> --dns <your-dns-record> --size 100users --affinity multitenant
i.e. in test account
cloud installation create --owner stelios --dns stelios.test.mattermost.cloud --size 100users --affinity multitenant

Check its creation progress on the first window where the API runs or run cloud installation list to check installation status

After the installation has finished(stable) you will be able to access your installation on your

Run the go tests to test:

$ go test ./...

Before deleting a cluster you will have to delete the installations first on it.

First, check how many installations are running:

cloud installation list
[
    {
        "ID": "8npnfpbiitygxbsrpg1p5i1sse",
        "OwnerID": "stelios",
        "GroupID": "",
        "Version": "stable",
        "Image": "mattermost/mattermost-enterprise-edition",
        "DNS": "stelios.test.mattermost.cloud",
        "Database": "mysql-operator",
        "Filestore": "minio-operator",
        "License": "",
        "MattermostEnv": null,
        "Size": "100users",
        "Affinity": "multitenant",
        "State": "creation-final-tasks",
        "CreateAt": 1589359071894,
        "DeleteAt": 0,
        "LockAcquiredBy": "m6sj6oc7fg93jkfgh3tjqw",
        "LockAcquiredAt": 1589359923924
    }
]

Get their IDs, and delete them

cloud installation delete --installation <installation-ID>
i.e.
cloud installation delete --installation 8npnfpbiitygxbsrpg1p5i1sse

Then proceed to cluster deletion:

cloud cluster delete --cluster <cluster-ID>

If a cluster cannot be deleted due to absence of ssh key, need to run:

kops create secret --name <cluster-ID>-kops.k8s.local sshpublickey admin -i ~/.ssh/id_rsa.pub --state s3://<your-s3-bucket>

Kops version 1.18.0 should introduce terraform 0.12 as the default version. Before migrating to the new terraform version, manual terraform state migration may be required. To perform a check if migration is needed, follow these instructions provided by kops:

kops update cluster --target terraform ...
terraform plan
# Observe any aws_route or aws_vpc_ipv4_cidr_block_association resources being destroyed and recreated
# Run these commands as necessary. The exact names may differ; use what is outputted by terraform plan
terraform state mv aws_route.0-0-0-0--0 aws_route.route-0-0-0-0--0
terraform state mv aws_vpc_ipv4_cidr_block_association.10-1-0-0--16 aws_vpc_ipv4_cidr_block_association.cidr-10-1-0-0--16
terraform plan
# Ensure these resources are no longer being destroyed and recreated
terraform apply

Tip: a quick and reliable way to get access to a cluster's terraform files and state is to use the cloud workbench cluster command. This will checkout the correct files locally in the same manner that the provisioning process uses.

This is related to the changes introduced in PR-263

Please follow the steps below for the reprovisioning of existing clusters:

• Reprovision the cluster by running cloud cluster provision --cluster <cluster_id> --nginx-version 2.15.0.
• Check that new nginx deployed both internal and public Load Balancers (nginx-ingress-nginx-controller-internal and nginx-ingress-nginx-controller).
• Manually update Prometheus Route53 record to use the new private Load Balancer (nginx-ingress-nginx-controller-internal).
• Manually update cluster installations Route53 records one by one to use the new public Load balancer (nginx-ingress-nginx-controller).
  • Update clusterinstallation ingress annotation to use Nginx class nginx-controller instead of nginx.
  • Manually update network policy to target nginx instead of public-nginx.
• Confirm that all services are up and running.
• Delete old NGINX helm charts.
  • helm del --purge public-nginx
  • helm del --purge private-nginx
