# Offline deployment
|
|
|
|
## manage-offline-container-images.sh
|
|
|
|
Container image collecting script for offline deployment
|
|
|
|
This script has two features:
|
|
(1) Get container images from an environment which is deployed online, or set IMAGES_FROM_FILE
|
|
environment variable to get images from a file (e.g. temp/images.list after running the
|
|
./generate_list.sh script).
|
|
(2) Deploy local container registry and register the container images to the registry.
|
|
|
|
Step(1) should be done online site as a preparation, then we bring the gotten images
|
|
to the target offline environment. if images are from a private registry,
|
|
you need to set `PRIVATE_REGISTRY` environment variable.
|
|
Then we will run step(2) for registering the images to local registry, or to an existing
|
|
registry set by the `DESTINATION_REGISTRY` environment variable. By default, the local registry
|
|
will run on port 5000. This can be changed with the `REGISTRY_PORT` environment variable
|
|
|
|
Step(1) can be operated with:
|
|
|
|
```shell
|
|
manage-offline-container-images.sh create
|
|
```
|
|
|
|
Step(2) can be operated with:
|
|
|
|
```shell
|
|
manage-offline-container-images.sh register
|
|
```
|
|
|
|
## generate_list.sh
|
|
|
|
This script generates the list of downloaded files and the list of container images by `roles/kubespray-defaults/defaults/main/download.yml` file.
|
|
|
|
Run this script will execute `generate_list.yml` playbook in kubespray root directory and generate four files,
|
|
all downloaded files url in files.list, all container images in images.list, jinja2 templates in *.template.
|
|
|
|
```shell
|
|
./generate_list.sh
|
|
tree temp
|
|
temp
|
|
├── files.list
|
|
├── files.list.template
|
|
├── images.list
|
|
└── images.list.template
|
|
0 directories, 5 files
|
|
```
|
|
|
|
In some cases you may want to update some component version, you can declare version variables in ansible inventory file or group_vars,
|
|
then run `./generate_list.sh -i [inventory_file]` to update file.list and images.list.
|
|
|
|
## manage-offline-files.sh
|
|
|
|
This script will download all files according to `temp/files.list` and run nginx container to provide offline file download.
|
|
|
|
Step(1) generate `files.list`
|
|
|
|
```shell
|
|
./generate_list.sh
|
|
```
|
|
|
|
Step(2) download files and run nginx container
|
|
|
|
```shell
|
|
./manage-offline-files.sh
|
|
```
|
|
|
|
when nginx container is running, it can be accessed through <http://127.0.0.1:8080/>.
