#If need install docker and Goland 
Start here.
#Install go
wget -c 'https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz' -O go1.10.3.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.10.3.linux-amd64.tar.gz
sudo rm -Rf go1.10.3.linux-amd64.tar.gz
#Set gopath
vi $HOME/.profile
#Add this lines to your file:
PATH=“$PATH:/usr/local/go/bin”
GOPATH=“$HOME/go”
PATH=“$PATH:$GOROOT/bin:$GOPATH/bin”
#reload profile
source $HOME/.profile
go version
#$: go version go1.10.3 linux/amd64
Step 2
#Install Docker
sudo apt-get update
curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh
sh install.sh
#Add your user to Docker Group
sudo usermod -aG docker $(whoami)
#Now that Goland and Docker is installed, just Download Cosmos Official repo.
go get github.com/cosmos/cosmos-sdk
#Open Cosmos Dir
cd go/src/github.com/cosmos/cosmos-sdk
#Build the Docker-Cosmos locally in the server
docker build -t CONTAINER-NAME .
#Example= docker build -t cosmos-026 .
#open a free Docker-Hub account
https://hub.docker.com/
#After opening the account, back to the server
#login in the server with your Docker-ID
docker login
#Tag the image for up to your Docker repo.
docker tag image username/repository:tag
#Ejample = docker tag cosmos-026 meleatrust/get-cosmos:part026
#Now up the Container image to your Docker repos.
docker push Docker-ID/docker-repo:Tag
#To see the container
docker image ls
#Great now you can use docker run and run your Cosmos-repo on any machine no need build again with this command:

Here one Back up file and instructions for sync the block +900k
Enjoy, more docker cmd comings later
post under constructions but verify for now is working ok. just need to add more cmd.
cheers 
Here two more Docker-Cosmos Post:
Happy dockerization
