So I have an API that's the gateway for two other API's.
Using docker in wsl 2 (ubuntu), when I build my Gateway API.
docker run -d -p 8080:8080 -e A_API_URL=$A_API_URL B_API_URL=$B_API_URL registry:$(somePort)//gateway
I have 2 environnement variables that are the API URI of the two API'S. I just dont know how to make this work in the config.
env:
- name: A_API_URL
value: <need help>
- name: B_API_URL
value: <need help>
I get 500 or 502 errors when accessing then in the network.
I tried specifyng the value of the env var as:
their respective service's name.
the complete URI (http://$(addr):$(port)
the relative path : /something/anotherSomething
Each API is deployed with a Deployment controller and a service
I'm at a lost, any help is appreciated
You just have to hardwire them. Kubernetes doesn't know anything about your local machine. There are templating tools like Helm that could inject things like Bash is in your docker run example but generally not a good idea since if anyone other than you runs the same command, they could see different results. The values should look like http://servicename.namespacename.svc.cluster.local:port/whatever. So if the service is named foo in namespace default with port 8000 and path /api, http://foo.default.svc.cluster.local:8000/api.

I am using Gitlab CI with docker executor and services.
During test I'm starting a server in the main script, and I need the service to make a request back to the main script.
Is there address/alias I can use to connect back to the main build script? Something like host.docker.internal.
Pseudo-example:
test:
services:
name: ping-pong-service
variables:
CALLBACK_ADDRESS: 'http://host.docker.internal:8090/pong'
script:
- "Start a server at 0.0.0.0:8090"
- curl http://ping-pong-service:80/ping
Supose that ping-pong-service is a service that when receiving any http request on :80, performs new request to CALLBACK_ADDRESS. What should I enter into CALLBACK_ADDRESS to connect back to main container?
I tried looking into what containers get started on the runner, but the main container doesn't seem to have predictable name or alias in the docker network.
Env:
Docker: 20.10.12
Gitlab Runner: 14.8.0, self-hosted, FF_NETWORK_PER_BUILD=1
Gitlab: 14.9.2-ee, self-hosted
When using the FF_NETWORK_PER_BUILD feature flag for networks per job, containers started using services: can reach the main job container using the network alias build
Assuming your service is configured as you describe, you would use:
variables:
CALLBACK_ADDRESS: 'http://build:8090/pong'
Note: this does not apply to containers started using docker run in the job container for this scenario.
My AUT runs in a docker container and the URL for it is "http://localhost:8080/" . Now when I trigger the tests using Zalenium it launches the browser but when it tries to navigate to the AUT's URL it can't find it. Is it because my AUT runs in a docker container and Zalenium also runs in a separate docker container and they both can't communicate with each other?
Thanks in Advance.
I think that's how it supposed to work. You ideally want contains to have isolation until you say otherwise.
A quick solution, on your selenium scripts, instead of localhost specify your <machine name>. That way, your scripts in zalenium will look to resolve the address through the network (which is still you) instead of trying to internally resolve localhost on their own network ring.
While this will probably work for you machine, it's a little bit static. You'll probably want to script it as part of your solution so it connects to multiple.
In java you can use this to get the running machine name:
InetAddress addr;
addr = InetAddress.getLocalHost();
hostname = addr.getHostName();
Alternatively, to make a more portable solution, you might want to review the docker networking pages.
I think this tutorial might help you. "Networking with standalone containers" sounds about right.
Long and short of it is when you run your docker containers you need to attach them to the same network. The default is:
--network bridge
Or create your own bridge:
docker network create --driver bridge MyBridgeName
and run both your containers on that bridge name:
docker run -dit --name MyImageName --network MyBridgeName ImageToRun
docker run -dit --name OtherName --network MyBridgeName OtherImageToRun
I am using the below command in jenkins to deploy the api proxies to apigee edge.
apigeetool deployproxy -u abc -o nonprod -e dev -n poc-jenkins1 -p xyz
But am getting the below error.
Error: Path /poc-deployment-automation conflicts with existing deployment path for revision 1 of the APIProxy poc-deploy-automation in organization nonprod, environment dev
Here is my requirement , please help me what command to use.
If API doesn’t exist in target environment, Create Api in new environment with version 1.
If API already exist in target environment, Create Api in new environment with new version (previous version + 1)
So what command should we use to fix the above error and what should we use to do the above 2 tasks.
Help Appreciated.
The apigeetool deployproxy command supports by default your requirements. It deploys the revision 1 if there is no proxy with the name, and increases the revision if it already exists.
However, based on the error you mentioned, it seems that you have a path conflict between two proxies. You are trying to deploy a proxy to a /poc-deployment-automation basepath, but there is another proxy called poc-deploy-automation which is listening on the same basepath. It is not possible, even if the proxy name is different, because the basepath is what apigee uses to redirect traffic to your proxy.
Check the xml file at the root of your proxy and change the basepath attribute.
Also, the basepath of an API Proxy can be anything, but could not be the same used at the same time by two proxies--only one can be deployed at time. The revision numbers are irrelevant in this situation.
i build spinnaker using docker-compose follow here
but it always redirect to localhost, how can i fix this.
e.g.
http://localhost:8084/auth/redirect?to=http%3A%2F%2F192.168.99.100%3A9000%2F%23%2Finfrastructure
i set the host:0.0.0.0 in spinnaker-local.yml and configured deck apache2 with proxyPreserve=On, it's not working.
where is the configuration about 'redirect'?
All containers running well but fiat gets error mesages, like this:
WARN 1 --- [ecutionAction-1] c.n.s.fiat.roles.UserRolesSyncer : [] User permission sync failed. Server status is DOWN. Trying again in 10000 ms. Cause:(Provider: DefaultServiceAccountProvider) retrofit.RetrofitError: unexpected url: front50/serviceAccounts
i'm sure set fiat false, is this matter?
thanks.
The docker-compose link project is not available anymore. That deployment type is not supported anymore.
The easiest way i suggest for people to get started quick is by using Armory Open source Minnaker. It runs on top of a K3S small cluster and contains a functional spinnaker deployment.
Great way to get started.
I tried the debian local deployment and it failed all the time.
Enjoy your CD operations.
Our team decided to try using OpenShift Origin server to deploy services.
We have a separate VM with OpenShift Origin server installed and working fine. I was able to deploy our local docker images and those services are running fine as well - Pods are up and running, get their own IP and I can reach services endpoints from VM.
The issue is I can't get it working, so the services are exposed outside the machine. I read about the routers, which suppose to be the right way of exposing services, but it just won't work, now some details.
Lets say my VM is 10.48.1.1. The Pod with docker container with one of my services is running on IP 172.30.67.15:
~$ oc get svc
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
my-svc 172.30.67.15 <none> 8182/TCP 4h
The service is simple Spring Boot app with REST endpoint exposed at port 8182.
Whe I call it from VM hosting it, it works just fine:
$ curl -H "Content-Type: application/json" http://172.30.67.15:8182/home
{"valid":true}
Now I wanted to expose it outside, so I created a router:
oc adm router my-svc --ports='8182'
I followed the steps from OpenShift dev doc both from CLI and Console UI. The router gets created fine, but then when I want to check its status, I get this:
$ oc status
In project sample on server https://10.48.3.161:8443
...
Errors:
* route/my-svc is routing traffic to svc/my-svc, but either the administrator has not installed a router or the router is not selecting this route.
I couldn't find anything about this error that could help me solve the issue - does anyone had similar issue? Is there any other (better/proper?) way of exposing service endpoint? I am new to OpenShift so any suggestions would be appirciated.
If anyone interested, I finally found the "solution".
The issue was that there was no "router" service created - I didn't know it has to be created.
Step by step, in order to create this service I followed the instructions from OpenShift doc page which were pretty easy, but I couldn't login using admin account.
I used default admin account
$ oc login -u system:admin
But instead using available certificate, it kept asking me for password, but it shouldn't. What was wrong? My env variables were reset, and I had to set them again
$ export KUBECONFIG="$(pwd)"/openshift.local.config/master/admin.kubeconfig
$ export CURL_CA_BUNDLE="$(pwd)"/openshift.local.config/master/ca.crt
$ sudo chmod +r "$(pwd)"/openshift.local.config/master/admin.kubeconfig
This was one of the first steps described in OpenShift docs OpenShift docs. After that the certificate is set correctly and login works as expected. As an admin I created router service (1st link) and the route started working - no more errors.
So in the end it came out to be pretty simple and dummy, but given that I didn't have experience with OpenShift it was hard for me to find out what is going on. Hope it will help if someone will have the same issue.
