Install PMM Server in isolated environments¶
To deploy PMM Server in air-gapped or isolated environments with no direct internet connectivity, download the Docker image on a separate (internet-connected) host and securely copy it:
- 
On an internet-connected host, download the Docker image and its checksum file: wget https://downloads.percona.com/downloads/pmm/3.4.1/docker/pmm-server-3.4.1.docker wget https://downloads.percona.com/downloads/pmm/3.4.1/docker/pmm-server-3.4.1.sha256sum
- 
Transfer both files to the target host where you’ll run PMM Server using a secure method (such as scp, physical media, or your organization’s approved file transfer mechanism).
- 
On the target host, open a terminal and navigate to where you placed the downloaded files. 
- 
Verify the Docker image file integrity (recommended): shasum -ca 256 pmm-server-3.4.1.sha256sum
- 
Load the Docker image: docker load -i pmm-server-3.4.1.docker
- 
Run the PMM Server container as if your image is already pulled using your desired method for a storage volume. Skip any docker pullcommands as the image has been pre-staged and available locally.
