HospitalRun – Docker Containerized

Hi Guys,

i just ran the containerized version of the HospitalRun Application on my digitalocean droplet using my own self signed certificate.

Please Watch my Youtube Video:-

apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add –

apt-key fingerprint 0EBFCD88

add-apt-repository \
“deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable”

apt-get update

apt-get install docker-ce docker-ce-cli containerd.io

apt-get install docker-compose

git clone https://github.com/HospitalRun/hospitalrun-server.git

openssl req -new -newkey rsa:2048 -nodes -keyout ssl.key -out ssl.csr

openssl x509 -req -in ssl.csr -signkey ssl.key -out ssl.crt

Docker – Add Proxy to Docker Daemon

I am gonna cut the chatter and hit the platter.

Proxy Recommendation :-  To Download the image from hub, we need internet connectivity.

I’ma show you the Steps to configure the proxy for Docker daemon.

1. Check the OS in which the docker-ce or docker-ee is installed.

ubuntu@docker:~$ cat /etc/*release*
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION=”Ubuntu 16.04.3 LTS”
NAME=”Ubuntu”
VERSION=”16.04.3 LTS (Xenial Xerus)”
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME=”Ubuntu 16.04.3 LTS”
VERSION_ID=”16.04″
HOME_URL=”http://www.ubuntu.com/”
SUPPORT_URL=”http://help.ubuntu.com/”
BUG_REPORT_URL=”http://bugs.launchpad.net/ubuntu/”
VERSION_CODENAME=xenial
UBUNTU_CODENAME=xenial

2. Check the Docker version

ubuntu@docker:~$ sudo docker -v
Docker version 17.05.0-ce, build 89658be

3. Create a directory

sudo mkdir -p /etc/systemd/system/docker.service.d

4. Create a Proxy Conf

vim /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment=”HTTP_PROXY=http://<proxy–ip>:<port>/”

Environment=”HTTPS_PROXY=https://<proxy–ip>:<port>/”

5. Now try to login to docker

ubuntu@docker:~$ sudo docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don’t have a Docker ID, head over to https://hub.docker.com to create one.
Username: <username>
Password:
Login Succeeded
ubuntu@docker:~$

 

Docker – Cheat Sheet

Hello Bloggers,

One of the most important thing in learning a new command quickly is going through the cheat Sheet.

I Love to go through Cheat Sheets for a quick references,

therefore i thought of consolidating some of the cheat sheets available online into my blog, for a quick ref.
