Offline container images provide a solution for scenarios where an internet connection may not be readily available or reliable.

The primary purpose of providing offline container images is to enable seamless and efficient Appcircle server installations and updates in situations where connectivity to online container registries is limited or restricted.

Here you will find how to use the Appcircle server's offline container images.


Software Requirements

To use the download or load commands, the self-hosted Appcircle server version must be 3.9.0 or later.

You need some tools for offline installation or upgrade. These are already installed if you followed one of the installation pages (Docker or Podman) and ran the command below.

sudo ./ -i

For Downloading From Another Machine

  • curl

For Loading Images On Appcircle Server Machine

  • curl
  • unzip
  • docker | podman

You must follow one of the Appcircle server installation methods (Docker or Podman) and configure global.yaml as your project's needs until the run server section.

Before running the server, you can install container images offline and then run the server.

Auth Requirement

During the installation of the self-hosted Appcircle server, it is essential to have the cred.json file provided to you upon purchasing the license. This cred.json file is necessary to access offline container images.

Without this file, you will not be able to access the offline container images required for the installation.

Configuration Requirement

You must configure your project before using offline container images.

Please refer to configuration section from our installation pages.

After you have configured your project, you can refer to this page to run your server with offline container images.


Install on a Server With No Internet Access

If your Appcircle server does not have access to any container registry and does not have internet access, you can still install the Appcircle server.

In this scenario, you should download the Appcircle server container images to another Linux machine that should have active internet access and copy them to the Appcircle server with any desired method, like ftp or scp.

For downloading the Appcircle server offline container images, you should download the latest Appcircle server package.


You should follow these steps on a Linux server that should have an active internet connection until you copy the container-images directory to the Appcircle server.

After copying the container-images directory to the actual Appcircle server, follow the remaining steps on the Appcircle server.

  • Go to the Appcircle server installation page.

  • Download the zip file and unzip it according to the instructions there.

  • Your organization should have a cred.json file. Copy that cred.json file inside the appcircle-server directory that you just unzipped.

  • Run the script with the download subcommand.

./ download
  • A file download process should start.

  • After the file download process has finished, you will see a directory named container-images in the appcircle-server directory.

  • You should copy this directory to the actual Appcircle server with any method you want, like ftp or scp.

  • After this step, you should login to the actual Appcircle server and go to the appcircle-server directory.

  • Now you should see the container-images directory, which is copied from the other machine, in the appcircle-server directory on the Appcircle server.

  • To import the container images into your project, run the load subcommand with the project argument.


The spacetech value in the code below is an example project name.

Please check your project name by listing the ./projects directory, and don't forget to replace the "spacetech" value with your project name.

./ -n "spacetech" load

After the load process completes, you should see the imported container images with your container engine.

If you are using Docker as container engine;

docker image ls

If you are using Podman as container engine;

podman image ls

Now you are ready to up (start) the Appcircle server. You can refer back to the Run Server section for details.

Install on a Server With Internet Access

If the container registry that your organization has is not reliable or has connection issues, you can download and install offline container images directly with internet access.

For this scenario to work, you should have an internet access on the Appcircle server.

Run the below command to install all required container images to your container engine.

./ -n "spacetech" load

If you have configured a custom registry url in global.yaml, downloaded images will be re-tagged with your custom registry url.

So the offline installation step is compatible with your custom registries.


This command will download container images and load them into the container engine that you use in your system. (Docker or Podman)

Now you are ready to up (start) the Appcircle server. You can refer back to the Run Server section for details.


If you installed a self-hosted Appcircle server before and you want to upgrade your self-hosted Appcircle server but you can't somehow download container images, you can update your container images with this method too.


If you are using the Appcircle DMZ structure and upgrading an Appcircle server, it is critical to also update the Appcircle DMZ server. If you don't, Enterprise App Store and Testing Distribution may not function as expected.

For more information about the DMZ structure, you can check the Appcircle DMZ documentation.


You don't need to change your global.yaml or reset your data.

Upgrading your Appcircle server with offline container images is fully compatible with your already-installed Appcircle server.

First, you need to update your self-hosted Appcircle server package. After you download and unzip the Appcircle server package, you can return to this page and follow the instructions below.

  • Go into the self-hosted Appcircle server directory.
cd appcircle-server
  • You can check the server version. So you will see which Appcircle server version images will be downloaded and loaded into the container engine.
./ --version
  • Shutdown the Appcircle server.
./ -n "spacetech" down

You should change the "spacetech" value in above command with your project name.

./ -n "spacetech" up
  • Check that your services are healthy and the Appcircle server is ready-to-use.
./ -n "spacetech" check
  • Check your image IDs and digests.
./ -n "spacetech" version

Those steps above will result in system downtime.

It is recommended to perform those operations during a maintenance window when users have been notified and there is no active usage of the system.

Ideally, scheduling the update for a time such as 03:00 am, when user activity is typically minimal, will minimize service disruptions.
