Eden is the simplest way to setup & test EVE and Adam.
Eden is inspired by Kubernetes workflows and CLI
All components of Eden -- the main executable file eden
and test binaries can be used as stand-alone applications without the need to install and configure the development environment on your computer. Generally, you will only need a text editor to configure the system and create test scenarios and scripts using eden
and pre-compiled test files. To create more complex tests, you can use standard Go testing machinery.
Eden contains series of integration tests implemented in Golang. Tests are structured as normal Golang tests by using _test.go
nomenclature and be available for test runs using standard go test framework.
Install requirements from eve
Also, you need to install telnet
and squashfs-tools
(squashfs
for Mac OS X).
You need to be able to run docker commands and able to access virtualization accelerators (KVM on Linux or machyve on Mac OS X)
git clone https://github.com/lf-edge/eden.git
cd eden
make build
eden config add default
eden setup
eden start
eden eve onboard
eden status
make build-tests
eden test
Note: Don't forget to call clean if you want to try the installation again.
Call either make clean
or
./eden stop
./eden clean --current-context=false
Note for cloud and VM users: eden and eve use virtualization. To run in VM-based environments, see the cloud document.
To find out what is running and where:
eden status
Eden's config is controlled via a yaml file, overriddable using command-line options. In most cases, the defaults will work just fine for you. For more informaton, see docs/config.md.
The main way to get a shell, especially once the device is fully registered to its adam
controller, is via ssh:
eden eve ssh
You can run a certain command remotely by passing it as argument:
eden eve ssh "ls -la"
If you need access to the actual device console, run:
eden eve console
Notice: if you are on QEMU there is a limited number of exposed ports. Add some if you want to expose more.
hostfwd:
{{ .DefaultSSHPort }}: 22
5912: 5901
5911: 5900
8027: 8027
8028: 8028
You can deploy images from different sources. In addition, eden deploys its own http server and docker registry.
Each source has its default format, but you can override it with the --format
flag. The defaults are:
docker://
- OCI imagehttp://
- VM qcow2https://
- VM qcow2 imagefile://
- VM qcow2 image
Deploy nginx server from dockerhub. Expose port 80 of the container to port 8028 of eve.
eden pod deploy -p 8028:80 docker://nginx
eden starts a local registry image, running on the localhost at port 5000
(configurable). You can start a docker image
from that registry by passing it the --registry=local
option. The default for --registry
is the hostname given
by the registry. For example, docker://docker.io/library/nginx
defaults to docker.io
. But if you pass it
the --registry=local
option, it will try to get it from the local, eden-managed registry.
eden pod deploy --registry=local docker://nginx
If the image is not available in the local registry, it will fail. You either can load it up (see the next section), or ask it to load and deploy:
eden pod deploy --registry=local --load=true docker://nginx
You can load the local registry with images.
eden registry load docker://docker.io/library/nginx
eden will do the following:
- Check if the image is in your local docker image cache, i.e.
docker image ls
. If it is, load it into the local registry and done. - If it is not, try to pull it from the remote registry via
docker pull
. Once that is done, it will load it into the local registry.
Deploy a VM from Openstack. Initialize root user with password - 'passw0rd' Expose port 22 of the VM (ssh) to port 8027 of eve for ssh:
eden pod deploy -p 8027:22 http://cdimage.debian.org/cdimage/openstack/current/debian-10.4.3-20200610-openstack-amd64.qcow2 -v debug --metadata='#cloud-config\npassword: passw0rd\nchpasswd: { expire: False }\nssh_pwauth: True\n'
Deploy a VM from a local file. This will cause the local file to be uploaded to the eden-deployed eserver
, which, in turn, will deploy it to eve:
eden pod deploy file:///path/to/some.img
Deploy a VM that is in a docker image, whether in OCI Artifacts format, or wrapped in a container. All formats from edge-containers are supported.
eden pod deploy docker://some/image:container-tag --format=qcow2
List running applications and their ip/ports
eden pod ps
To see logs of app you should get name (app_name
in the example bellow) of it and run
eden pod logs app_name
You can choose information to display by providing --fields
flag from the list (or define multiple fields separated by the comma):
log
- to view log objectsinfo
- to view info objectsmetric
- to view metric objectsapp
- to view console output
You can show only N last lines by setting of --tail
flag.
eden runs EVE using a live.img
file with an embedded config partition, which eve configures. In a normal
run, eden takes care of getting and installing an eve OS disk image for you. However, you can configure eden
to use a different image. This is particularly useful for eden's primary use case: testing EVE.
To work with custom EVE images, see docs/eve-images.md.
To run tests make sure you called make build-tests
.
The easy way to run tests is to call eden test <test folder>
For example -- run reboot test:
eden test tests/reboot/
Some tests may accept parameters - run Log/Metrics/Info test in debug mode with timeout of 600 seconds and requiring 3 messages of each type
eden test tests/lim/ -v debug -a '-timewait 600 -number 3'
You can find more detailed information about eden test
in tests/README.md and tests/escript/README.md
Eden is enough to deploy Eve on Google Cloud. We are going to make it one command, but now the process is:
- Make an image
- Upload it to GCP and run
- start eden (if not started yet)
- Onboard eve (use
eden eve onboard
)
Step 1 : Make an image. You need to specify IP of Adam, by defalut Adam is a container inside machine with Eden, so put there an IP that is accessible from gcp
make build
./eden config add default --devmodel GCP
./eden config set default --key adam.eve-ip --value <IP of Adam/Eden>
./eden setup
Step 2 : Upload image to gcp and run it. You will need a google service key json. https://cloud.google.com/iam/docs/creating-managing-service-account-keys
./eden utils gcp image -k <PATH TO SERVICE KEY FILE> -p <PROJECT ON GCP> --image-name <NAME OF IMAGE ON GCP> upload <PATH TO EVE IMAGE>
./eden utils gcp vm <PATH TO SERVICE KEY FILE> -p <PROJECT ON GCP> --image-name <NAME OF IMAGE ON GCP> --vm-name=<NAME OF VM ON GCP> run
eden utils gcp
also supports
- --bucket-name for images
- --machine-type for vm
Step 3 : Configure the firewall and make sure ADAM is exposed in the network Note that the firewall may be active on GCP. Allow connections (create rules)
extIP=$(gcloud compute instances describe <GCP VM NAME> --format='get(networkInterfaces[0].accessConfigs[0].natIP)' --zone=us-west1-a)
gcloud compute firewall-rules create <RULE NAME> --allow all --source-ranges=$extIP
ADAM should be publicly available from GCP machine.
Step 4 : Start eden and onboard Eve
./eden start
./eden eve onboard
Eden is the only thing you need to work with Raspberry and deploy containers there:
Step 1: Install EVE on Raspberry instead of any other OS.
Prepare Raspberry image
git clone https://github.com/lf-edge/eden.git
cd eden
make build
eden config add default --devmodel RPi4
eden setup
eden start
Then you will have an .img that can be transfered to SD card. https://www.raspberrypi.org/documentation/installation/installing-images/
For example for MacOS:
diskutil list
diskutil unmountDisk /dev/diskN
sudo dd bs=1m if=path_of_your_image.img of=/dev/rdiskN; sync
sudo diskutil eject /dev/rdiskN
Put in SD card into Raspberry and power it on
Step 2: Connect to Raspberry and run some app.
eden eve onboard
eden pod deploy -p 8028:80 docker://nginx
After these lines you will have nginx available on public EVE IP at port 8028
Use
eden status
eden pod ps
to get the status of the deployment
To get information from SD card about previously flashed instance of EVE you should:
Step 0 (for MacOS): Install required packets after installing of brew:
brew cask install osxfuse
brew install ext4fuse squashfuse
Step 1: List partitions.
For MacOS diskutil list
For Linux lsblk
You should find your SD and 5 partitions on it.
Step 2: Mount partitions of SD card on your PC
For MacOS (diskN
is SD card from step 1)
sudo umount /dev/diskN*
sudo squashfuse /dev/diskNs2 ~/tmp/rootfs -o allow_other
sudo ext4fuse /dev/diskNs9 ~/tmp/persist -o allow_other
For Linux (sdN
is SD card from step 1)
mkdir -p ~/tmp/rootfs ~/tmp/persist
sudo umount /dev/sdN*
sudo mount /dev/sdN2 ~/tmp/rootfs
sudo mount /dev/sdN9 ~/tmp/persist
Step 3: Extract files and save them:
- syslog.txt contains logs of EVE:
sudo cp ~/tmp/persist/rsyslog/syslog.txt ~/syslog.txt
- eve-release contains version of EVE:
sudo cp ~/tmp/rootfs/etc/eve-release ~/eve-release
Step 4: Umount and eject SD
For MacOS
sudo umount /dev/diskN*
sudo diskutil eject /dev/diskN
For Linux
sudo umount /dev/sdN*
sudo eject /dev/sdN
You can get more information about make
actions by running make help
.
More information can be found at the wiki or in the #eve-help channel in slack.
Eden is controlled by a single command named (in a secret code) eden
. It has multple sub-commands and options.
Run eden help
to see sub-commands.
To build eden
:
make build
To build eden
and tests inside eden
It's better to call eden config add
first, so the build command can build tests for the desired architecture
make build-tests
You can build it for different computer architectures and operating systems by passing OS
and ARCH
options.
The default, however, is for the architecture and OS on which you are building it.
make build OS=linux
make build ARCH=arm64
The generated command is place in ./dist/bin/eden-<arch>-<os>
, for example eden-darwin-amd64
or eden-linux-arm64
.
To ease your life, a symlink is placed in the local directory named eden
for your current architecture and OS.
The current sub-commands are:
config
-- work with different configurations of environment;status
-- get status of all components;setup
-- get all components that are specified in the config and ensure they are ready for startup;start
-- start all componentsstop
-- stop all components;clean
-- cleanup EDEN artifacts (images and certificates) for current context. If you want to clean artifacts of all contexts, you should to runclean --current-context=false
;test
-- run tests;info
-- displays Info records, accepts regular expression as a filter;log
-- displays Log records, accepts regular expression as a filter;metric
-- displays Metric records, accepts regular expression as a filter ;eve
-- sub-commands for interact with EVE.controller
-- sub-commands to update EVE.pod
-- work with applications running on EVE (containers and VMs)network
-- sub-commands to work with networks running on EVE
