Get Mattermost running in minutes
Install Mattermost from the VPSnet Applications catalog, claim secrets in the panel, open when HTTPS is ready, and finish initial setup in the app — without SSH as the default path.
Order a server and install
Order Cloud VPS or VDS, or open an existing service. Install Mattermost from Applications — safe defaults apply when the recipe allows.
Claim one-time secrets in the panel
Usernames and passwords appear once in the VPSnet panel after install. Copy them when the credentials window opens — they are never emailed.
Open when HTTPS is ready
Most apps use managed HTTPS on a *.vpsnet.cloud host. Wait until the certificate is active, then Open URL from the panel — certificate pending is not an install failure.
Complete initial setup in the app
Sign in with the secrets you claimed (or finish the in-app admin wizard). Complete one real job for Mattermost. If you enabled Optional packs at install, finish each pack’s first-run inside the app. Restart, logs, update, and uninstall stay in the Applications panel.

How to install Mattermost on VPSnet
Managed install of Mattermost from the Applications panel — credentials in-panel, HTTPS included.
- 01. Choose a plan for MattermostOpen the Mattermost product page and note minimum and recommended vCPU, RAM, and disk. Order a new Cloud VPS or VPS, or use a running server that still has free capacity.
- 02. Install from ApplicationsIn the service panel open Applications → Mattermost → Install. Choose an access mode and expand Additional settings. If a customer-editable password field is offered, enter your own strong value or leave it empty for VPSnet to generate a random one. Confirm a runtime restart if the panel asks.
- 03. Save one-time credentialsWhen install finishes, the panel shows owner or admin credentials once. Copy them into your password manager immediately — they are never sent by email. If you closed the dialog too early, use the recovery path on that install in Applications.
- 04. Open the managed HTTPS URLWhen Mattermost exposes a web UI, VPSnet assigns a *.vpsnet.cloud hostname. A short Certificate pending state is normal while DNS and SSL finish. When the status is active, use Open URL in Applications.
