"Opkg update" fails in LXC container

Hey Community,

I'm investigating the creation of LXC type containers.

I operated according to "Docker Images and Packages Repository".

https://developer.cisco.com/docs/iox/#!docker-images-and-packages-repository

Accessing the repository using docker daemon

[Step.1:Login to the Cisco devhub using generic user credentials.]

<<CODE SNIPPET>>

$ docker login -u iox_docker.gen -p AKCp2WX2yZXhwiQXG2xZjHvnrov8HA2HkXZyH3Z46ErGNMDz1fHQKAMRCBbEvseLowd7BQ8S1 devhub-docker.cisco.com

WARNING: login credentials saved in /home/user/.dockercfg.

Login Succeeded

<<Execution result>>

$ docker login -u iox_docker.gen -p AKCp2WX2yZXhwiQXG2xZjHvnrov8HA2HkXZyH3Z46ErGNMDz1fHQKAMRCBbEvseLowd7BQ8S1 devhub-docker.cisco.com

Error response from daemon: Get https://devhub-docker.cisco.com/v2/: unauthorized: BAD_CREDENTIAL

<<QUESTION>>

Is the password changed?

Please tell me the correct password.

[Step.2:Pull the docker image based on the target architecture using 'docker pull' command.]

<<CODE SNIPPET>>

$ docker pull devhub-docker.cisco.com/iox-docker/ir800/base-rootfs

<omitted below>

<<Execution result>>

$ docker pull devhub-docker.cisco.com/iox-docker/ir800/base-rootfs

Using default tag: latest

latest: Pulling from iox-docker/ir800/base-rootfs

c8e49009c524: Pull complete

Digest: sha256:f14bed751e384496ca40645c8221990bc1ab8fec6cae53b452ae09e2e91db0d4

Status: Downloaded newer image for devhub-docker.cisco.com/iox-docker/ir800/base-rootfs:latest

<<QUESTION>>

Login to devhub failed but 'docker pull' worked.

Are there any problems with this procedure?

[Step.3:Running the image]

<<CODE SNIPPET>>

$ docker run -it devhub-docker.cisco.com/iox-docker/ir800/base-rootfs /bin/sh

Unable to find image 'devhub-docker.cisco.com/iox-docker/ir800/base-rootfs:latest' locally

latest: Pulling from iox-docker/ir800/base-rootfs

<omitted below>

/ #

<<Execution result>>

$ docker run -it devhub-docker.cisco.com/iox-docker/ir800/base-rootfs /bin/sh

/ #

<<QUESTION>>

no problem.

Because I pull the image in Step 2,

<<QUESTION>>

Have I affected by failing login to devhub at Step.1?

It seems that the password used in Step 1 differs from the password described in "opkg.conf" of the pull image,

but can it be different?

Since "apt-get update" succeeds in the execution environment, I think that there is no problem with the network.

Re: "Opkg update" fails in LXC container

I happen to see someone asked similar question and the solution :

Hope this can address your issue too.

`````````````

We have already identified this issue where anyone logged-in with the generic credential could change the API key and it will break the access to the devhub. Currently we are working on it and testing the open access to devhub repo where we could avoid this issue. Meanwhile as workaround can you add this line in the dockerfile before using opkg instructions:

RUN sed -i 's/\(option http_auth iox_docker.gen:\).*/\1AKCp5bAif2Tzg1MtWAJbLoTXweosuqqSgSEyKApikowUq5sycevTsK7LcQ7EKLbzQFuyc9WCk/' /etc/opkg/opkg.conf

Re: "Opkg update" fails in LXC container

To be honest, I don't know which key to use can you please try the following if not working then I will ask subject matter expert for you.

RUN sed -i 's/\(option http_auth iox_docker.gen:\).*/\1AKCp5bAt1aQQR9L3dk4FP6QLDjd9XYhZLuhCLaHuwYnoGmDPLc584stTT6cWSeNdYavPR3wAV/' /etc/opkg/opkg.conf

Cisco Employee

Re: "Opkg update" fails in LXC container

please use the latest.

The API key was updated after that and currently active key is  “AKCp5bAt5nK9nJBeq1nFe3Ywntfokny8f1oHeTYpLrGCYG9iv9P3gkX9KFj6wzHcQoLkwP5Pa”

Re: "Opkg update" fails in LXC container

Hi,yawchen

Thank you for your cooperation.


I was able to build successfully.


I also found a way to check the current API - Key in the devhub web UI.

It is frightening for anyone to regenerate API-Key.

Thank you.

Re: "Opkg update" fails in LXC container

Face the same issue,how can I find the right API-key ? which relevant steps in https://developer.cisco.com/docs/iox/#!docker-images-and-packages-repository/overview should I follow.Thanks a lot

Re: "Opkg update" fails in LXC container

I just want to point out that the correct line in th Dockerfile has to be:

RUN sed -i 's/\(option http_auth iox_docker.gen:\).*/\option http_auth iox_docker.gen:AKCp5bAt5nK9nJBeq1nFe3Ywntfokny8f1oHeTYpLrGCYG9iv9P3gkX9KFj6wzHcQoLkwP5Pa/' /etc/opkg/opkg.conf

Note: If the API Key changes the above line has to be adjusted.
