Habor installer thinks docker-compose is not installed

Question

I m trying to install Harbor 2.4.1 on a CentOS 7 host. I have already installed docker and docker-compose. But wenn I try to run ./install.sh to instal harbor I get the message

[grafra1969@docker-registry harbor]$ sudo ./install.sh --with-notary --with-trivy --with-chartmuseum

[Step 0]: checking if docker is installed ...

Note: docker version: 20.10.12

[Step 1]: checking docker-compose is installed ...
✖ Need to install docker-compose(1.18.0+) by yourself first and run this script again.
[grafra1969@docker-registry harbor]$ ls ..
certs  harbor  harbor-online-installer-v2.4.1.tgz  harbor-online-installer-v2.4.1.tgz.asc

Docker and docker-compose are available. What is the problem?

this is a bug/issue with the composer installation, I just had the same problem and managed to fix it by running:

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

and then to prevent the installer from overwriting the symlink you just created you will need to remove the docker and docker-compose installation from the installer.

You should have a sh file that looks something like this:

#!/bin/bash

#Harbor on Ubuntu 18.04

#Prompt for the user to ask if the install should use the IP Address or Fully Qualified Domain Name of the Harbor Server
PS3='Would you like to install Harbor based on IP or FQDN? '
select option in IP FQDN
do
    case $option in
        IP)
            IPorFQDN=$(hostname -I|cut -d" " -f 1)
            break;;
        FQDN)
            IPorFQDN=$(hostname -f)
            break;;
     esac
done

# Housekeeping
apt update -y
swapoff --all
sed -ri '/\sswap\s/s/^#?/#/' /etc/fstab
ufw disable #Do Not Do This In Production
echo "Housekeeping done"

#Install Latest Stable Harbor Release
HARBORVERSION=$(curl -s https://github.com/goharbor/harbor/releases/latest/download 2>&1 | grep -Po [0-9]+\.[0-9]+\.[0-9]+)
curl -s https://api.github.com/repos/goharbor/harbor/releases/latest | grep browser_download_url | grep online | cut -d '"' -f 4 | wget -qi -
tar xvf harbor-online-installer-v$HARBORVERSION.tgz
cd harbor
sed -i "s/reg.mydomain.com/$IPorFQDN/g" harbor.yml
./install.sh --with-clair --with-chartmuseum
echo -e "Harbor Installation Complete \n\nPlease log out and log in or run the command 'newgrp docker' to use Docker without sudo\n\nLogin to your harbor instance:\n docker login -u admin -p Harbor12345 $IPorFQDN"

After all of this you can check if you have docker and docker-compose installed by running them with no commands and if they are indeed installed you can now run the new installer sh file.

Also, add yourself to the docker group using sudo usermod -a -G docker <YOUR_USER> just to make sure that's not the issue.

My Problem was caused by the fact that I installed docker-compose in /usr/local/bin. I assumed this would be a good location, since it was in the PATH of my user and in the PATH of user root. However I did not consider, that sudo uses a different PATH. This secure path is configured in /etc/sudoers and does not contain /usr/local/bin. So I deceided to move the docker-compose script to /usr/bin and the installer worded fine.
