Docker-openvpn: The file '/etc/openvpn/vars' was not found

[yell0w4x]

Looks like kylemanna/openvpn:latest is broken. Also kylemanna/openvpn:2.3 works fine.

$ docker run -v $OVPN_DATA:/etc/openvpn --log-driver=none --rm -it kylemanna/openvpn ovpn_initpki

Easy-RSA error:

The file '/etc/openvpn/vars' was not found.

[valerioferretti92]

Same thing happened to me.

[anthonymobile]

for the dummies like me

docker run -v $OVPN_DATA:/etc/openvpn --log-driver=none --rm kylemanna/openvpn:2.3 ovpn_genconfig -u udp://vpn.yourdomain.com
docker run -v $OVPN_DATA:/etc/openvpn --log-driver=none --rm -it kylemanna/openvpn:2.3 ovpn_initpki

[yell0w4x]

Also kylemanna/openvpn:2.3 works fine.

The issue is about kylemanna/openvpn:latest

[RafayAK]

The same also happing to me, will try @joeky888 reference

[RafayAK]

using 2.3 works

[joshuacox]

hmmm, I can get the image running by using the 2.3 tag, but upon trying to create a client:

Easy-RSA error:

EASYRSA_PKI does not exist (perhaps you need to run init-pki)?
Expected to find the EASYRSA_PKI at: /etc/openvpn/pki

@kylemanna hi, i've been using the 2.4 tag from dockerhub for months now without any problem. I see now that you overwrote the 2.4 tag on dockerhub just 14 days ago. Are you aware of the problem described in this thread?

[kylemanna]

@ebarault I'm not aware of what the problem remaining is. I fixed a number of issues most importantly the CI tests running on Tavis-CI. No issues are reported on the branch that docker tag points to:

https://travis-ci.org/github/kylemanna/docker-openvpn/builds/741565318

Does the problem remain? Can you show me details like docker image hash + error?

[kylemanna]

Pretty sure this is fixed, someone can let me know if it's not true. CI builds pass and they'd fail on this if it was a problem.

Hi Kyle,

Thanks a lot for the hard work on this project.

I was finding a similar issue with a fork of your repo, but it seems to be an issue with EasyRSA, not any of your binaries.

It's fixable by running the easyrsa_export binary, pointing to /etc/openvpn/vars. Then, init_pki will work fine:

bash /usr/local/bin/easyrsa_vars export > /etc/openvpn/vars
bash /usr/local/bin/ovpn_initpki

Picked up from references below:

StackOverflow
..and its related article
easyrsa_vars script

---

Hopefully this should point people having the same issue towards the right direction. I haven't inspected your code yet to see if this is referenced anywhere and if it's skipped somehow.

Cheers!

[kylemanna]

I understand this was an issue, but I've updated many thing to resolve things like this. Can anyone show me the exact steps to reproduce this on any Docker Hub hosted image (must include hash of image)?

The Travis-CI builds work fine with new images and I'm convinced this problem was resolved sometime ago until someone can show me more.

[ebarault]

Hi @kylemanna
with image 4fa457dfce43

I had to use this trick
touch /etc/openvpn/vars

Why is this issue closed? Just checked back, the problem is still there.

@kylemanna here are the images loaded on my computer:

Here are their hashes:

veeveisb@veeveisb-OptiPlex-7010:~/Desktop$ docker inspect kylemanna/openvpn:latest | jq '.[0].Id'
"sha256:d5a2586f86e0d3aff02efc8abc147a1e784c5ef7a8b8a0940ba03faa0d11b6fa"
veeveisb@veeveisb-OptiPlex-7010:~/Desktop$ docker inspect kylemanna/openvpn:2.4 | jq '.[0].Id'
"sha256:4fa457dfce432adb384a04f268cd4b9b73b5d1f660e857a114a2505bbd71ef6e"
veeveisb@veeveisb-OptiPlex-7010:~/Desktop$ docker inspect kylemanna/openvpn:2.3 | jq '.[0].Id'
"sha256:f0a0813c5240026ec823d5aab4393f4674cac553fe1f2a7004e8b3dc4bf1ad01"

Following are the results of creating a client using different image tags:

• with kylemanna/openvpn:latest

• with kylemanna/openvpn:2.4

• with kylemanna/openvpn:2.3

As you can see only the image with the tag 2.3 passes successfully the rest fail.

[kylemanna]

@RafayAK thanks for sharing, now I understand what's going wrong.

Can you build the dev image and test it?

$ git fetch origin
$ git checkout origin/dev
$ docker build -t openvpn-test .

Then run the same command replacing kylemanna/openpvn:2.4 with openvpn-test and share your result. Once I hear this works I can merge the dev branch and close this issue for good.

[RafayAK]

I'll try this tonight.

[RafayAK]

@kylemanna This seems to do the trick!

I created an image as you suggested:

Ran the command:

docker run -v $OVPN_DATA:/etc/openvpn --log-driver=none --rm -it openvpn-test easyrsa build-client-full $CLIENTNAME nopass

Now just to check if revocation and removal of a generated client key passes I also ran this command:

docker run --rm -it -v $OVPN_DATA:/etc/openvpn openvpn-test ovpn_revokeclient ${CLIENTNAME} remove

The output looks like this as follows:

This output is slightly different when compared to kylemanna/openvpn:2.3:

docker run --rm -it -v $OVPN_DATA:/etc/openvpn kylemanna/openvpn:2.3 ovpn_revokeclient ${CLIENTNAME} remove

The last 3 lines which show what files were removed is not showing, probably not a big deal though.
Either way thanks for fixing this.

PS. Let me know if you need me to run anymore tests

[kylemanna]

@RafayAK thanks for testing, I'll merge dev branch into master and 2.4 branches and this will go away. Thanks for providing actionable logs and testing 👍🏼

[kylemanna]

@RafayAK #621 should fix this for you, can you try re-pulling and confirm? I think we can call this closed!
