Download Docker Offline
Dibe Naro
Is there any way for me to download Docker images from the hub as a file that I could then sneaker-net to my dev workstation? Similar to how I can download RPMs or Ruby Gems and burn them to CD? Or is the only way of downloading the images using the 'docker pull' command?
I have installed docker in a system which has no connection to Internet so to run an image with docker, I had to download a simple image from this and from another system. Then I put this image in my offline system in this path : C:\Users\Public\Documents\Hyper-V\Virtual hard disks
Yes, you can use Docker Desktop offline. However, youcannot access features that require an active internetconnection. Additionally, any functionality that requires you to sign in won't work while using Docker Desktop offline or in air-gapped environments.This includes:
The host has a changing IP address, or none if you have no network access.We recommend that you connect to the special DNS name host.docker.internal,which resolves to the internal IP address used by the host.
tl;dr:dont change the exposed ports of your docker container, especially port 8080. Leave it as it is. Also, add the docker host IP in your unifi controller settings (in the new UI under settings>system>scoll down for 'override inform host'>enable and add '192.168.1x.x', your docker host ip)
Second important note is to add your Docker host IP address in the Unifi Controller Settings. I could not really find, how the Settings entry is named in the new UI Version, so I first switched to legacy UI, added the IP and switched back to the new UI. Here is where you add the IP without switching to the old legacy UI:it's in settings>system>scoll down for 'override inform host'>enable and add '192.168.1x.x', your docker host ip
so that is what I cannot do on local machine - fetch an image from registry-1.docker.io/v2/ - e.g. I have to prepare my own php image, apache image, postgres image etc. And point my docker to fetch these images locally, not from Docker Hub.
I have a project consisting of about ten docker images which I deploy with docker-compose.
Since the new pull limits are in effect this has come to be very inconvenient because I reach the pull limit of 200 pulls for registered users every day with tests deployments. It seems docker and docker-compose do pull requests every time I build/update a docker image, although the images I derive my Images from are accessible from my local repository (i.e. they are shown by docker image ls).
Is there some kind of offline mode for docker so that even the faintest idea of pulling for new image versions does not appear to docker?
I have to enter in the container because, the permanent directory is not created before i start the container (and the tomcat). So i cant put this instruction before the catalina start. I did it by scripting in the docker entry point but its the same result in all case.
EDIT: adding domain: .local to my ESPHome code changed nothing. Dashboard still shows as offline and clicking the logs button just says it could not resolve .local and pinging the same from a computer works.
I had a similair issue. All my noded were reachable via name e.g. desklamp.home.lan. after i set the domain to .home.lan . Esphome kept showing the devices as offline. It didnt seem capable of resolving the devices. This is how ended up on this forum post. after some googling i found the esphome faq docker references. there is enviromental variable to be set.
wow, what a can of worms I just opened. did an update to home assistant this morning - home assistant os 8 and core 2022.5.4. after update, esphome shows no errors in logs, but all devices offline, and lights and everything is not working. I tried this use the ping setting above and after restarting devices show online for a couple seconds and start falling off one at a time.
Pi-hole now translates the hostname of the esphome node into the IP address for any client that uses it as a DNS server. Because my docker container uses the synology NAS host networking and my Synology NAS uses Pi-hole for DNS, the docker can now resolve the hostname to the IP address and the viewing of live logs as well as the online status works.
I am late to the party, but maybe this could help someone if other methods do not work.
I have a similar setup with a dedicated vlan for IOT devices which all of my esphome nodes are on.
My esphome dashboard was showing all devices offline.
All I did was:
For this article, we are only going to work with the nginx image. Onthe manager node, grab images using command: docker image pull - thenginx image itself is 109MB. No big deal when moving at 60mph, right?!
ok good, can you confirm that you have in the backup directory /opt/xibo/shared/backup/db (in my config) the 2 backup files latest.sql.gz and previous.sql.gz ?
Can you check aswell you have enough disk space ?
Do you run docker-compose with sudo ?
I have a floating license for KSE and KRE as well, the KRE is in offline mode, I have a separate server which contain the KRE, the issue I am facing that I got error message when I try to run test throw docker images and the same error when I try to run it from GitLab CI CD.
My config docker work fine, i can see the login page for user and admin. My container PHP is link with container DB with good env variables, and i have modified ost-config.php with define('DBHOST','db');
Update: I found a workaround which always (reproducibly!) solves the problem, though the workaround confirms my thought that there has to be a neat solution to the problem: Every time when I just re-create the entire stack in docker (without changing anything) the Z-Wave stick gets recognized again.
Removing the lock file is needed, if it is left, but that is (at least in my case) not the full solution, at least not if I just restart oH. Maybe if I restart the full machine. But since I run oH on a server doing lots of other stuff, I prefer to just try to restart oH a gazillion times until the serial port is working again. But it can literally take hours of trying in worst case. Maybe this alone is a reason for start using docker with oH.
The download_packs_and_docker_images script enables offline users to download content packs and the content pack's latest Docker images to their computer and upload these packs and images to their Cortex XSOAR environment.
The download_packs_and_docker_images.py script is located in the Utils folder in the GIT Content repository. If you do not have access to the GIT Content repository, you can download the script from here.
1Q. Does the RHEL 7 installation come with docker already on it? If not, where do I get it from? (I cannot use the docker software at docker.com, it has to come from RedHat - government rules, not mine)
1A. Based off of Hunter's comment, No, docker does not come with Red Hat; however, on a internet-connected system you can use the reposync command to download all of the RPMs from the RH Extras Channel using repoID: rhel-7-server-extras-rpms. Then by creating the repo data using createrepo command in the directory that contains the Packages directory. A good instruction set can be found here. Then you can transfer the data to the air-gapped system.
2A. Once you transfer the data RH Extras RPM data to the air-gapped system with minimal installation, you will need to install the some back-end tools: yum, yum-utils, and createrepo. Here is a good instruction set on how to do this. Once you get those tools installed you should be able to follow these instructions here to get docker installed.
An offline, or air-gapped, environment provides higher security than online, connected environments. As the offlineenvironment has no outside communication, the only method to install Sisense in this environment is by usingremovable media, such as USB drives.
The offline installation package includes the Sisense installer. The installer must be configured to point to your Docker registry. When you run the installer, Sisense pushes Sisense-related Docker images to your local registry, which are then pulled by your K8S cluster when Sisense is installed on the cluster.
The process for installing Sisense requires you to complete two procedures:
I'm trying to install docker on a Windows Server 2016 VM that's not connected to the internet. The official docker documentation doesn't give any advice for installing on a Windows Server 2016 VM without the internet, so how can I achieve this?
I read a blog somewhere that said it was sufficient to download the docker.exe and dockerd.exe files and place them in C:\Windows\System32, then running dockerd.exe --register-service was sufficient to install Docker. While this appears to have "worked" (docker info has output), trying to pull down an image from my local registry fails (it just freezes with no error output). Additionally, I notice that there is no DockerNAT NIC setup, and I'm going to guess that there are other steps missing that I'm unaware of.
I am using docker to run my application which is spring boot restful webservice.Can i use jacoco to fetch report after manual/automation test finish to check how much code we are hitting via QA team.I started docker container via passing JAVA_OPTS=-javaagent:/opt/jacoco/lib/jacocoagent.jar=output=tcpserver,address=*,port=6300 . and i can connect to via jacococli to get dump java -jar /opt/jacoco/lib/jacococli.jar dump --address localhost --destfile /tmp/jacoco.execnow geting report out of dump file i need to pass classfile also but hence i am running images how i can pass class files.If my question is not clear let me know i will try to put it in other way i need to resolve same on high priority, Thanks.
The installation has also to coexist with everything else on the PC - as I will want to use OON in conjunction with other software on the machine, whether that is other software is more Docker images/containers, or just normal desktop offline software.
Thanks
