Import Docker Images for an Offline Installation of the PubSub Beat

To install docker images, which allows for Open Collector to operate offline, do the following:

Remove the previous versions.yml file if one exists.
BASH
```
 rm -f versions.yml
```

Download and copy all the artifacts below to the virtual machine.

S. No.	Component	Link	Checksum
1	lrctl	lrctl_6_4_0.tar	lrctl_6_4_0.tar.sha256
2	open-collector	opencollector_5_5_4.tar	opencollector_5_5_4.tar.sha256
3	metrics	metrics_6_0_1.tar	metrics_6_0_1.tar.sha256
4	versions.yml	versions.yml	versions.yml.sha256
5	lrctl(script)	lrctl_script	lrctl_script.sh.sha256
6	alpine	Alpine.tar	alpine.tar.sha256
7	docker 20.10.8	docker_20_10_8.tar.gz	docker_20_10_8.tar.sha256
8	pubsubbeat	pubsubbeat_6_0_1.tar	pubsubbeat_6_0_1.tar.sha256

Before extracting the .tar files into docker images, Docker must be installed.

If the Docker is already installed, skip to step 6.

Extract docker_20_10_8.tar.gz:
BASH
```
tar xzvf /path/to/docker_20_10_8.tar.gz
```
Move the binaries to /usr/bin/:
BASH
```
cp docker/* /usr/bin/
```
Start the Docker Daemon:
BASH
```
dockerd &
```
Before downloading the artifacts, remove any running container(s) and the images related to that container.
1. To stop all the running components, run the following command:
  BASH
```
docker rm -f $(docker ps -aq)
```
2. Next, remove all the docker images in the system:
  BASH
```
docker rmi -f $(docker images -aq)
```
To extract a docker image from a .tar file, use the following command:
BASH
```
docker load < <image-name>.tar
```
Repeat step 7 to extract any additional .tar files.
Place lrctl and versions.yml in the same folder.
Execute this command after step 9.
BASH
```
./lrctl autoupdate disable
```

Use "-V versions.yml" with every command while working with the beat.

BASH

./lrctl -V versions.yml pubsubbeat start

Once all the .tar files have been extracted, start the Open Collector and PubSub Beat as normal by following the steps at .Configure the PubSub Beat v2021.12.
