Permission changed to 1000 on local host after Docker container with volume created

由 喜你入骨 提交于 2019-12-08 11:06:17
问题 After my container is created with external volume, Permission becomes 1000. drwxr-x--- 7 1000 1000 4096 Mar 02 01:13 my_domain Everytime i need to changed it my user. AS docker is installed by root user. How can i avoid this situation ? Can anyone please write something ? 回答1: With docker host volumes, you will see the UID of the user inside the container used to read and write files on the host, there is no translation of UID/GID between the container and host (that's not a feature of linux

What will happen after the maximum number of images pushed to ECR repository

问题 According to Amazon ECR Service Limits, the maximum number of images per repository is 1,000. After exceeding this limit, the oldest image won't remove automatically. It blocks pushing to the repository. So I have to clean old images manually. Update: AWS introduced ECR Lifecycle Policies. We can now automate the cleanup with this. 回答1: Having experienced this exact scenario, I can confirm that upon reaching the limit, AWS will block you from pushing with this very unhelpful error message:

Does docker reuse images when multiple containers run on the same host?

由 可紊 提交于 2019-12-07 03:23:49
问题 My understanding is that Docker creates an image layer at every stage of a dockerfile. If I have X containers running on the same machine (where X >=2) and every container has a common underlying image layer (ie. debian), will docker keep only one copy of the base image on that machine, or does it have multiple copies for each container? Is there a point this breaks down, or is it true for every layer in the dockerfile? How does this work? Does Kubernetes affect this in any way? 回答1: Dockers

Missing log lines when writing to cloudwatch from ECS Docker containers

由 老子叫甜甜 提交于 2019-12-05 23:36:51
问题 (Docker container on AWS-ECS exits before all the logs are printed to CloudWatch Logs) Why are some streams of a CloudWatch Logs Group incomplete (i.e., the Fargate Docker Container exits successfully but the logs stop being updated abruptly)? Seeing this intermittently, in almost all log groups, however, not on every log stream/task run. I'm running on version 1.3.0 Description: A Dockerfile runs node.js or Python scripts using the CMD command. These are not servers/long-running processes,

How to configure a Docker container for acquiring DHCP IP/s from dhcp server running on ESX

由 怎甘沉沦 提交于 2019-12-05 23:08:14
问题 My host is SLES12 VM running on an ESX server. VM Host has interfaces which acquire DHCP IPs from the DHCP server running on ESX. In my docker container (docker image: opensuse) I am running a NFS server and hence need external access. I want the container to acquire dhcp IP from the dhcp server running on ESX (just like my Host VM gets). I have tried pipework but could not get it working. Here is what I did: Enabled Promiscuous mode on ESX. Created new bridge (br1) and attached it to Host

Huge files in Docker containers

由 淺唱寂寞╮ 提交于 2019-12-04 10:25:35
问题 I need to create a Docker image (and consequently containers from that image) that use large files (containing genomic data, thus reaching ~10GB in size). How am I supposed to optimize their usage? Am I supposed to include them in the container (such as COPY large_folder large_folder_in_container )? Is there a better way of referencing such files? The point is that it sounds strange to me to push such container (which would be >10GB) in my private repository. I wonder if there is a way of
