What should I do if the dependent image cannot be pulled, or the inner environment cannot access docker.io?

Answer: here are two solution to solve this problem

  • Solution 1: In the network that can access docker.io, transfer the image in the command kubevpn version to your own private image registry, and then add option --image to special image when starting the command. Example:
➜  ~ kubevpn version
KubeVPN: CLI
    Version: v2.0.0
    DaemonVersion: v2.0.0
    Image: docker.io/naison/kubevpn:v2.0.0
    Branch: feature/daemon
    Git commit: 7c3a87e
    Built time: 2023-09-30 22:01:51
    Built OS/Arch: darwin/arm64
    Built Go version: go1.20.5

Image is docker.io/naison/kubevpn:v2.0.0, transfer this image to private docker registry

docker pull docker.io/naison/kubevpn:v2.0.0
docker tag docker.io/naison/kubevpn:v2.0.0 [docker registry]/[namespace]/[repo]:[tag]
docker push [docker registry]/[namespace]/[repo]:[tag]

Then you can use this image, as follows:

➜  ~ kubevpn connect --image [docker registry]/[namespace]/[repo]:[tag]
Starting connect

Getting network CIDR from CNI...
Getting network CIDR from services...
...
  • Solution 2: Use options --transfer-image, enable this flags will transfer image from default image to --image special address automatically。 Example
➜  ~ kubevpn connect --transfer-image --image nocalhost-team-docker.pkg.coding.net/nocalhost/public/kubevpn:v2.0.0
v2.0.0: Pulling from naison/kubevpn
Digest: sha256:450446850891eb71925c54a2fab5edb903d71103b485d6a4a16212d25091b5f4
Status: Image is up to date for naison/kubevpn:v2.0.0
The push refers to repository [nocalhost-team-docker.pkg.coding.net/nocalhost/public/kubevpn]
