@Roshan ^ also, what happens when you run sudo dockerd?

Thanks guys, that issue is resolved. I have updated terraform template, under docker_container section I have added privileged = true and rebuild the workspace after that I can able to use docker. I'm facing below issue while doing networking with docker inside devcontainer: vscode ➜ /workspaces/hyperledger/fabric-samples/test-network (main) $ ./network.sh up Using docker and docker-compose Starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb' LOCAL_VERSION=v2.5.12 DOCKER_IMAGE_VERSION=v2.5.12 WARN[0000] /workspaces/hyperledger/fabric-samples/test-network/compose/compose-test-net.yaml: the attribute version is obsolete, it will be ignored, please remove it to avoid potential confusion WARN[0000] /workspaces/hyperledger/fabric-samples/test-network/compose/docker/docker-compose-test-net.yaml: the attribute version is obsolete, it will be ignored, please remove it to avoid potential confusion [+] Running 0/3 ⠙ Container orderer.example.com Starting 0.1s ⠙ Container peer0.org1.example.com Starting 0.1s ⠙ Container peer0.org2.example.com Starting Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint peer0.org2.example.com (9ae407712bf7593a0a5e30386b0657d7c1e8d59b3f1aaf2055fb4843066ee72e): Unable to enable DIRECT ACCESS FILTERING - DROP rule: (iptables failed: iptables --wait -t raw -A PREROUTING -p tcp -d 172.19.0.2 --dport 9051 ! -i br-b4dfe5cceafd -j DROP: iptables v1.8.7 (legacy): unknown option "--dport" Try `iptables -h' or 'iptables --help' for more information.

hey, while this does work, i would very well recommend installing sysbox instead running privileged containers is very unsafe

check this out https://coder.com/docs/admin/templates/extending-templates/docker-in-workspaces#sysbox-container-runtime

Docker in Workspaces | Coder Docs

Use Docker in your workspaces

Phorcys•5w ago

try switching to sysbox, it should fix that

RoshanOP•4w ago

I tried this, facing above issue

Phorcys•3w ago

how have you installed sysbox?

RoshanOP•3w ago

you mean on the host machine?

Phorcys•3w ago

yeah cc @Roshan

Danielle•3w ago

@Roshan On the host machine, what does your docker config look like? This is what mine looks like and I can run the following

$ cat /etc/docker/daemon.json
{
        "runtimes": {
                "sysbox-runc": {
                        "path": "/usr/bin/sysbox-runc"
                }
        }
}
