recording the user's historical resource usage

We need to periodically record the resource usage of the user's all containers, especially the CPU usage.
Note that for a container named ct, if we stop it and restart it, the lxc-info -n ct command will only get the current usage info from the restarting time. The previous history usage info will get lost. So we need a deliberate design to record all the historical resource usage.

unable to show and edit user table in smartphone

Can only display a part of the user table, unable to scroll the table

vlanid share

the user in fundation group should share vlanid

time display in UserList

The register date displayed seems to be in UTC time, which is not convenient for non UTC timezone users. @PedroLiu

The image save time and workspace start time is using EastAsia/Shanghai timezone, which is possibly the default setting of the physical host.

So @PedroLiu should at least display the time using default timezone.

And maybe we should let admin specify timezone docklet uses, then show time according to this timezone? @zhongyehong

display file size, modification time in jupyter notebook

fork from https://github.com/jupyter/notebook, add feature of displaying file size, modification time, using this version notebook in docklet base image.
finally try submit a pull request to notebook.

Can't stop vcluster by dashboard page

After starting a container, we can't stop it.

Admin panel

I create this issue in "Os Practice" milestone to respond to the OS practice course. Fanshixiong chooses this topic, @zhongyehong.

Many settings are now in docklet.conf. The problem is that the settings only take effect at master start time. But some settings should allow modification and should take effects immediately after getting modified. Therefore, there should be an admin panel, allow administrators to change system settings.

We could discuss which configuration should be placed here.

Lists:

The user token expiration time in #48

[guest] delete guest dashboard

disable StrictHostKeyChecking for ssh

so that mpi and spark cluster will not ask for host key checking.

add LXCFS for container

with lxcfs, /proc filesystem in container is able to show the quota limited by cgroup, instead of showing the host hardware information.

bug of external login

external login failed and nothing output

nfs mountpoint bug in imagemgr.py

We have moved nfs mountpoint from / to /root, but i have not changed the rsync parameter in imagemgr.py

rsync -a --delete --exclude=nfs/

it should be

rsync -a --delete --exclude=root/nfs/

i will fix it today or tomorrow.

subprocess call should check return status

not just calling sys_run and assume it will execute correctly. sometimes it will fail and the failure info will get lost.

display quota in Status page

show user's quota information in their status pages.

VLAN & VxLAN

add a new panel to approve or decline user activation requests

Administrators could simply decline or approve the activation requests by click a button. Also the administrators can give some reasons why the requests declined.

Not Found error when just click "Sign in" Button

If the user leaves username and password empty, just click "Sign in" button, he will get a "Not Found" error.

Not Found

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

enhance quota management

quota management enhancements

• more quota item, like disk quota.
• save quota information in separate json file

Making workers's state consistent with master

This is a succeeding issue of #8. Currently if we restart master, we need not to restart workers. But if we initialise the master, the workers will not work correctly. Therefore, we need to make the workers consistent with the master, regarding whether the master being restarted or initialised.

Default proxy port should be 80

Not 8000.

add quota easily and able to remove quota group

• can remove a quota group
• can add quota with just one click with no need to edit the detailed quota item

Big File Upload

Big File Upload for OS practice

display container owner

In the Node list for host x.x.x.x, the ** PID ** field is valueless. So please replace it with the user's Truename, which could be more helpful.

Fail to create container

After starting the master and worker, it is reported by master that "container created failed". And in the worker's log, it is reported that there is an error at line 133 in "container.py". The log is "ERROR container[133] 'disk' ".

updating user profile taking effects immediately

changing nickname, avatar, description should take effects immediately.

add a button in index.html linking docklet.unias.org

so users can visit docklet homepage more easily

the mountpoint of tmp

tmp should be mounted from host folder，not use the space of lvm.

[user] token expires after some time

User Token should expire after some time, and then user need to login again.

logging user's activity

the web module should log user's activity, but not sensitive information, such as pass.

Show disk usage in Summary of container

Current Status table is :

Current Status:

Name	State	IP Address	CPU Use	CPU Quota	Mem Use
0006175153-30-0	Running	172.16.0.54	78.63 seconds	2 Cores	0.80% (122.45MiB/15258.79MiB)

could be

Current status of 0006175153-30-0:

State	IP Address	CPU Usage	Mem Usage	Disk Usage
Running	172.16.0.54	78.63 seconds (2 Cores)	0.80% (122.45MB/15258.79MB)	60% (1200MB/2000MB)

[network] check IP and network pool when releasing IPs

Now, we not check whether IPs are in network pools when releasing IPs.
This may cause some IP pools have duplicated IPs.

For example, someone may double click the delete button of one workspace and IPs of this workspace will be released twice.

So, checking IP and network pools is necessary.

rewrite httprest.py using flask routing

move system data to global/sys

move UserTable, quota, and other system level data to global/sys

Event Driven Tasks

Event Driven Tasks Arch discussion of OS practice course.

subprocess should check

check typing and input on web pages and web server

We should check whether typing on web pages is valid.
And checking input of web server is necessary.

For example, user may name workspace 'My Homepage no.1'. But space character is not valid for workspace name. This may cause user unable to start workspace.

support lxc.custom.conf in appending

lxc.custom.conf should be appended in container.conf
not replace container.conf

Make the Logout and Profile buttons clear

The Profile and Logout buttons has no background colour, therefore are easy to be neglected. Please make them clear.

give user a total quota, let themselves decide how to use quota

when creating a container, give them a choice and a default config, they can choose to create one strong container, or several weak containers. strong container will cost more resources (we will use bean to measure the cost), while weak container cost less.

[monitor] status page of normal user failed

status page of normal user failed.

I have saw the code of httprest.py and the bug is in line 348 ~ line 380.

The code below self.response will be executed also, except you put return after self.response.

For normal user, status page will request httprest with /monitor/user/quotainfo, I think line 349 of httprest.py should be executed but line 355 should not be executed. Right? So, you should fix this soon.

@FirmlyReality

independent starting of master and workers

Currently the workers must be started after the master, which is not reasonable. The workers should be able to start even if the master has not started, and wait for the master joining in. In other words, the administrator can restart the master without restarting the workers.

lxc config string in config file is limited in 16 bytes

lxc config string should be less than 16 bytes.
For example, if lxc.network.veth.pair is 'leebaokleebaok-0', container will start failed.

Now, we use UserName-ID-Offset as lxc.network.veth.pair and this may exceed the limited length.

typo error of group name fundation

It should be foundation, but not fundation.
