GitLab with Docker on Synology NAS - HTTPS - docker

I would like to set up GitLab with https on Synology DS918+.
I am using DOCKER in DSM. I downloaded the latest GitLab Community docker image.
And I used Putty to ssh into the NAS and create keys using openssl.
1) Create a key into cert folder:
mkdir /volume1/docker/gitlab/certs
cd /volume1/docker/gitlab/certs
openssl genrsa -out gitlab.key 2048
openssl req -new -key gitlab.key -out gitlab.csr
openssl x509 -req -days 3650 -in gitlab.csr -signkey gitlab.key -out gitlab.crt
openssl dhparam -out dhparam.pem 2048
chmod 400 gitlab.key
2) I added two additional variables in custom image to set up the environment for HTTPS:
3) In the last part:
I remove port 80 that was first set in the default image.
And add ports 30000/30001 for 22/443 port bindings that were set to auto in the default image:
When I go to browser for https://synologyip.com:30000 GitLab can't be reached.
Any guesses on what have I missed or done wrong?
Thanks!

I don't know about you, but I had to create the cert in the following folder:
/volume1/docker/gitlab/gitlab/certs
Note the repeated gitlab directory

A good well-written tutorial can be found here: Github Tutorial, and with a letsencrypt cert too!
Although i shortened the cert copy part like follows:
cat /usr/syno/etc/certificate/_archive/*/privkey.pem > /volume1/docker/github/github/certs/gitlab.key
cat /usr/syno/etc/certificate/_archive/*/fullchain.pem > /volume1/docker/github/github/certs/gitlab.crt
and continued then with the dhparam.pem

Running Bamboo Server over HTTPS with Self-Signed Certificate

Bamboo server is running on Docker Container (linux) with the Public image.
docker pull atlassian/bamboo-server:latest
It's accessible at http://localhost:8085, but we want to use HTTPS with a self-signed certificate to run our Bamboo Server. Could you please explain the steps for "how to secure Bamboo server running on Docker Container with HTTPS"? I read the Atlassian article, but it does not appear to contain enough information.
We can use Ngnix (if necessary), but I haven't started because I'm not familiar with the configuration.
Despite the fact that I generated the.keystore file on the Docker host and used the environment to map with the container:
{$JAVA_HOME keytool -genkey} or
{openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 365}
docker run -d -v bambooVolumeLatest:/var/atlassian/application-data/bamboo --init -p 54663:54663 -p 8443:8443 -e JVM_MINIMUM_MEMORY=3g -e JVM_MAXIMUM_MEMORY=3g -e ATL_TOMCAT_SCHEME=https -e ATL_TOMCAT_SECURE=true -e ATL_TOMCAT_SSL_ENABLED=true -e ATL_TOMCAT_SSL_PROTOCOL=TLS -e ATL_TOMCAT_KEYSTORE_FILE=/root/.keystore -e ATL_TOMCAT_KEYSTORE_PASS=changeit atlassian/bamboo
it's throwing an error:

Any help would be much Appricieated.
thsi does the trick for me (docker-compose file)
environment:
- JVM_MINIMUM_MEMORY=4000m
- JVM_MAXIMUM_MEMORY=8000m
- ATL_TOMCAT_PORT=8443
- ATL_TOMCAT_SSL_ENABLED=true
- ATL_TOMCAT_SCHEME=https
- ATL_TOMCAT_SECURE=true
- ATL_TOMCAT_SSL_CERTIFICATE_FILE=/opt/atlassian/bamboo/conf/ssl/xxxxxx.com.crt
- ATL_TOMCAT_SSL_CERTIFICATE_KEY_FILE=/opt/atlassian/bamboo/conf/ssl/xxxxxx.com.key
volumes:
- bamboo:/var/atlassian/application-data/bamboo
- ./ssl:/opt/atlassian/bamboo/conf/ssl
I don't bother with the keystore, on linux systems, be sure the files are owned by 2005:2005 (bamboo user in docker). cert & key can be retrieved with
openssl pkcs12 -in xxxxx.com.pfx -out xxxxx.com.pem -nodes
if you dig around a bit you can also find how to pull it from pem, good luck!

Asp.net core, "asn1 encoding routines:asn1_d2i_read_bio:not enough data" error for certificate

When running my asp.net core application locally in my Linux Docker container, the following error occurs:
Unhandled exception. Interop+Crypto+OpenSslCryptographicException: error:0D06B08E:asn1 encoding routines:asn1_d2i_read_bio:not enough data
at Internal.Cryptography.Pal.OpenSslX509CertificateReader.FromBio(SafeBioHandle bio, SafePasswordHandle password)
at Internal.Cryptography.Pal.OpenSslX509CertificateReader.FromFile(String fileName, SafePasswordHandle password, X509KeyStorageFlags keyStorageFlags)
... when instanciating an X509Certificate2 object in my startup.cs:
services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true).AddEntityFrameworkStores<ApplicationDbContext>();
var identityServerBuilder = services.AddIdentityServer().AddApiAuthorization<ApplicationUser, ApplicationDbContext>();
var certificate = new X509Certificate2(#"abc.pfx", "abc"); // This is where the exception is thrown.
identityServerBuilder.AddSigningCredential(certificate);
I need this self-signed certificate to run IdentityServer4.
When debugging in Visual Studio I have no problems and I can perfectly evaluate all of the pfx's properties.
I generated the pfx file on Linux as follows:
openssl genrsa -out rsa.private 1024
openssl req -new -key rsa.private > rsa.csr
openssl x509 -req -in rsa.csr -signkey rsa.private -out rsa.crt
openssl pkcs12 -export -in rsa.crt -inkey rsa.private -out abc.pfx
...and verifying its integrity:
openssl pkcs12 -nokeys -info -nocerts -in abc.pfx
... revealed no problems:
MAC: sha1, Iteration 2048
MAC length: 20, salt length: 8
PKCS7 Encrypted data: pbeWithSHA1And40BitRC2-CBC, Iteration 2048
Certificate bag
PKCS7 Data
Shrouded Keybag: pbeWithSHA1And3-KeyTripleDES-CBC, Iteration 2048
I also used the Microsoft Management Console to generate the pfx, but that results in the same error.
I'm mounting my pfx file executing this Docker run command:
docker run -d=false -p 8080:80 -v abc.pfx:/app/abc.pfx --name mijncont mijncont:dev
My appsettings.json :
"IdentityServer": {
"Clients": {
"TEST.Client": {
"Profile": "IdentityServerSPA"
}
},
"Key": {
"Type": "Store",
"StoreName": "My",
"StoreLocation": "LocalMachine",
"Name": "CN=mijnsubject"
}
When running :
docker exec -it mijncont /bin/bash
... the following prompt appears :
root#3815c63cb5c4:/app#
When executing 'ls -la'
I get this :
drwxr-xr-x 2 root root 4096 Jul 13 16:04 abc.pfx
However when I include this line in my Startup.cs :
Console.WriteLine("Size: "+ new System.IO.FileInfo("abc.pfx").Length);
... .Net throws an exception saying that the file doesn't exist.
I included the directory containing the pfx file in Docker -> Settings -> Resources -> File sharing
Anyone?
The problem lied in the way I mounted my abc.pfx file.
This :
docker run -d=false -p 8080:80 -v abc.pfx:/app/abc.pfx --name mijncont mijncont:dev
...mounts a directory called abc.fpx in the container (holding the abc.pfx file)
If I specify an absolute path :
docker run -d=false -p 8080:80 -v C:\mysolution\abc.pfx:/app/abc.pfx --name mijncont
...only the file is mounted to the 'app' directory which is what I want.

Docker TLS - How to create key on local machine

Pre knowledge:
So I started using docker myself and installed it on my server and enabled TLS. I followed this tutorial: https://docs.docker.com/engine/security/https/
This tutorial will eventually give you 6 files:
-r-------- ca-key.pem
-r--r--r-- ca.pem
-r--r--r-- cert.pem
-r-------- key.pem
-r--r--r-- server-cert.pem
-r-------- server-key.pem
The owner of these files is root. I copied the ca.pem, cert.pem and key.pem, I used them to connect from my local portainer instance. (Actually I only use cert.pem and key.pem since I only have client verification on)
DOCKER HOST:
{
"hosts": [
"unix:///var/run/docker.sock",
"tcp://0.0.0.0:2376"
],
"storage-driver": "overlay2",
"tls": true,
"tlscacert": "/etc/docker/certs/ca.pem",
"tlscert": "/etc/docker/certs/server-cert.pem",
"tlskey": "/etc/docker/certs/server-key.pem",
"tlsverify": true
}
My problem:
The company where I work installed docker for me and enabled TLS, put all the pem files in a directory which I can access... Problem is, I cannot download the key.pem since the owner is root and I won't get access to it.
I can download the next files:
ca.pem
cert.pem
server-cert.pem
Is is possible for me; with access to those files ONLY, not changing anything on the server, to access docker over TLS? How can I create my own key.pem, or is there another way?
Sorry if this is common knowledge, I just could not find my answer anywhere, or I did not know what I was exactly searching for...
Yes, you can work against the docker-daemon on that server and you don't need to create another key and certificate for the server.
Download the server-cert.pem and export the following environment variables in your local session:
DOCKER_TLS_VERIFY="1"
DOCKER_CERT_PATH="server-cert.pem"
DOCKER_HOST= "tcp://HOST:2376"
Now you can use your local docker-client and work against the docker-daemon on your server. e.g. docker ps should display containers running on the remote docker.
Private keys create the certificates, you can't create a key from a cert. If your docker wants a 2 way authentication you will need access to the private key. It cannot be done without.
You'll need the following files (for client-server authentication):
ca.pem
cert.pem
key.pem

Copying SSL certificate with Ansible

I'm trying to copy an SSL certificate from an Ansible host VM to a Docker host VM,and i keep having the following error
FAILED! => {"changed": false, "msg": "Template source files must be utf-8 encoded"}
the playbook is simple and has only two steps:
- name: Create directory for SSL certificate
file: path=/etc/ssl/certs/pm state=directory
- name: Copy SSL certificate from Ansible host to Docker host
template:
src: inventories/staging/files/pm.jks
dest: /etc/ssl/certs/pm/pm.jks
owner: root
mode: 0755
ignore_errors: true
When i replace pm.jks with an empty file with the same name and extension,the copying works fine,so clearly there's a problem with the format of its content. but i'm not sure how to fix this.
I'm using this command to generate the certif :
keytool -genkey -alias pm -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore pm.p12 -genkey -alias pm -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore pm.p12 -validity 3650
Why not use the file method of Ansible instead the template module? The error is quite clear - you cannot use the template module, because the source file you are referencing is not UTF-8 encoded.
If you examine the file you created with the command you posted, you will notice that it is a binary file:
test#toor:~$ file pm.p12
pm.p12: data
test#toor:~$ less pm.p12
"pm.p12" may be a binary file. See it anyway?
Either try using a different Ansible module or try saving the file in a plain text format.
Just because I stumbled over it searching for the same solution.
Here an excerpt from my playbook where I used the builtin copy module
# playbook.yaml
- name: Create path for SSL cert
file: path=/etc/ssl/certs/custom state=directory
- name: Copy SSL cert
ansible.builtin.copy:
src: /path/to/local/my_cert.p12
dest: /etc/ssl/certs/custom/my_cert.p12
owner: root
mode: 0644

Docker private registry using selfsigned certificates

I want to run a private docker registry which is widely available.
So I will be able to push and pull images from other servers.
I'm following this tutorials: doc1 & doc2
I performed 3 steps:
First I've created my certificate and key (as CNAME I filled in my ec2-hostname)
mkdir -p certs && openssl req \
-newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \
-x509 -days 365 -out certs/domain.crt
Than I've created my docker registry, using this key.
docker run -d -p 5000:5000 --restart=always --name registry \
-v `pwd`/certs:/certs \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
registry:2
Than I copied the content of domain.crt to /etc/docker/certs.d/ec2-xx-xx-xx-xx.compute.amazonaws.com:5000/ca.crt
I restarted my docker: sudo service docker restart
When I try to push an image I get the following error:
unable to ping registry endpoint https://ec2-xx-xx-xx-xx.compute.amazonaws.com:5000/v0/
v2 ping attempt failed with error: Get https://ec2-xx-xx-xx-xx.compute.amazonaws.com:5000/v2/: net/http: TLS handshake timeout
v1 ping attempt failed with error: Get https://ec2-xx-xx-xx-xx.compute.amazonaws.com:5000/v1/_ping: net/http: TLS handshake timeout
I really don't know what I'm missing or doing wrong. Can someone please help me. Thanks
I'm not sure if you copy/pasted your pwd directly... but the file path should be /etc/docker/certs.d
You currently have etc/docker/cert.d/registry.ip:5000/domain.crt
The error message says "TLS handshake timeout". This indicates that either no process is listening on port 5000 (check using netstat) or the port is closed from the location where you are trying to push the image (open port in the AWS security group).
From what I've seen docker login is way more sensitive to properly crafted self-signed certs than browsers are + there's an interesting gotcha I'll point out at the very bottom, so read the whole thing.
According to this site:
https://jamielinux.com/docs/openssl-certificate-authority/create-the-root-pair.html
Bash# openssl x509 -noout -text -in ca.crt
X509v3 Basic Constraints: critical
CA:TRUE
^You should see something like this is you provisioned your certs right.
While following random how-to guides on the net I was able to generate ca.crt and website.crt
When I ran the above command I didn't see that output, but I noticed:
If I imported the cert as trusted in Mac or Win my browser would be happy and say yeap valid cert, but docker login on RHEL7 would complain with messages like)
x509: certificate signed by unknown authority
I tried following directions related to using: /etc/docker/certs.d/mydockerrepo.lan:5000/ca.crt
on https://docs.docker.com/engine/security/certificates/
It got me a better error message (which caused me to find the above site in the first place)
x509: certificate signed by unknown authority (possibly because of
"x509: invalid signature: parent certificate cannot sign this kind of
certificate" while trying to verify candidate authority certificate
After 2 days of messing around I figured it out:
When I was taught programming I was taught the concept of a short self-contained example, so going to try doing that here for ansible, leveraging the openssl built-in modules, I'm running latest ansible 2.9, but this should work for ansible 2.5++ in theory:
Short Self Contained Example:
#Name this file generatecertificates.playbook.yml
#Run using Bash# ansible-playbook generatecertificates.playbook.yml
#
#What to Expect:
#Run Self Contained Stand Alone Ansible Playbook --Get-->
# currentworkingdir/certs/
# ca.crt
# ca.key
# mydockerrepo.private.crt
# mydockerrepo.private.key
#
#PreReq Ansible 2.5++
#PreReq Bash# pip3 install cryptograph >= 1.6 or PyOpenSSL > 0.15 (if using selfsigned provider)

Interesting Gotcha/Final Step:
RHEL7Bash# sudo cp ca.crt /etc/pki/ca-trust/source/anchors/ca.crt
RHEL7Bash# sudo update-ca-trust
RHEL7Bash# sudo systemctl restart docker
The gotcha is that you have to restart docker, for docker login to recognize updates to CA's newly added to the system.
